That is indeed a very interesting behavior. I could not reproduce this issue with UE v18.10.0.1010.

It looks like this behavior has something to do with a feature based on syntax highlighting. Therefore I suggest first to open a *.html file and reproduce this issue. If it can be indeed reproduced, use File - Revert to Saved to restore original file contents, click on No Highlighting in submenu View as (Highlighting File Type) in menu View and try to reproduce this behavior again.

Does this strange behavior not happen anymore with syntax highlighting and all associated features disabled for the file?

I suppose the answer is: yes, it cannot be reproduced with syntax highlighting disabled.


As for HTML files multi-language syntax highlighting is enabled by default, it would be interesting if this deletion of characters occurs in a HTML section or in another section. In the status bar at bottom of UltraEdit main window the string HTML indicates that at current position of caret in text the HTML syntax highlighting is active. The string CSS 1.0-2.1 would indicate that CSS highlighting is active, JavaScript indicates JavaScript syntax highlighting active, and so on.

I can think of three features which change words and are based on syntax highlighting.

The first one is auto-correction enabled with setting Auto-correct keywords at Advanced - Configuration - Editor Display - Miscellaneous. But I don't think this setting is responsible for that strange behavior as it just corrects the case of letters of a word and not delete characters. Further it changes a word always immediately and never on deletion of characters. However, verify if this setting is enabled and if this is the case, check behavior with this setting unchecked.

The second one is the smart templates feature. I suggest to open Advanced - Configuration - Templates and uncheck setting Auto-suggest smart template when typing and try next to reproduce the unexpected behavior. Does disabling this feature disable also the unwanted behavior? Yes, I suppose something is wrong with language templates for HTML. Look what is configured on the other computer for templates in UltraEdit and compare %APPDATA%\IDMComp\UltraEdit\templates\language\html-tpl.xml of the two computers. The original HTML template file html-tpl.xml is located in subdirectory template\language in program files directory of UltraEdit. Therefore it is possible to compare also the used HTML template file %APPDATA%\IDMComp\UltraEdit\templates\language\html-tpl.xml with the original template file %ProgramFiles%\IDM Computer Solutions\UltraEdit\template\language\html-tpl.xml (on 32-bit Windows XP and standard installation).

The third one is Automatically close XML/HTML tags located at Advanced - Configuration - Editor - XML/HTML. Verify if this setting is enabled and if this is the case, check behavior with this setting unchecked. I don't think that this feature is responsible for the deletion of the word on deletion of a character, but give it a try.

Last but not least the syntax highlighting wordfile for HTML itself can be corrupt. Compare original HTML wordfile %ProgramFiles%\IDM Computer Solutions\UltraEdit\wordfiles\html.uew with used HTML wordfile %APPDATA%\IDMComp\UltraEdit\wordfiles\html.uew.


You could also copy entire directory %APPDATA%\IDMComp\UltraEdit while UltraEdit is not running on computer where this problem does not occur to the other computer on which this directory is first renamed to UltraEdit_Backup before pasting the working configuration into directory %APPDATA%\IDMComp. If %APPDATA%\IDMComp\UltraEdit_Backup contains a subdirectory license with file uedit32.spl, this file should be copied over %APPDATA%\IDMComp\UltraEdit\license\uedit32.spl as the license file is unique for each computer.

Start UltraEdit and try to reproduce the strange behavior. Can it still be reproduced or does the deletion of characters not occur anymore?

In case of problem cannot be reproduced anymore, it would be interesting which files are different in the two application data directories of UltraEdit and investigate them to find out what caused this unwanted behavior of deletion of characters after deleting a single character.

I stop here with my suggestions on determining the cause of this issue. Let us know if anything above has helped already and which suggestion has helped.

Best regards also to Bavaria.

It is very, very strange that turning off syntax highlighting and enabling it again solves the problem on a file. I think, something is wrong with the *.uew files.

I suggest to close project/workspace if there is one currently opened. Next close all files. Then open Advanced - Configuration - Toolbars / Menus - Miscellaneous, click on button Clear history, close configuration dialog with Cancel and exit UltraEdit.

Now compress entire directory %APPDATA%\IDMComp\UltraEdit to a ZIP or RAR archive.

Restart UltraEdit and check if the problem can be still reproduced with a *.html file which best does not contain confidential data.

If the problem can be reproduced with that file after starting UltraEdit with clearing all history entries from uedit32.ini, add this *.html file also to the ZIP or RAR archive. Post a new reply with appending the ZIP or RAR file as attachment. I will download it and look on your configuration files what cause this strange behavior. As I wrote already, I think the reason can be found somewhere in the *.uew files and I would be really interested in what causes this strange behavior.

Glad to read that the problem is solved and which file caused the bad behavior. Now we have a reference for looking up for other users in case seeing same strange behavior. Thanks for final report and which steps solved the problem.
