I am using UltraEdit in Windows 11 environment. 
There was no such problem before, but after the Microsoft IME (Input Method Editor) was updated in Windows 11, when I input Korean in UltraEdit, the second character is not written. (Letters are displayed across 1, 3, 5, 7 like this.) 
A workaround for this issue is to enable the use of older IMEs in the Microsoft IME.
But I don't want to solve the problem like this. 
The Windows Mail program built into Windows has had a nasty IME bug for years. 
The changed Windows 11 Microsoft IME this time is the patched version of this bug. (Enabling an older version of the IME reproduces this bug.)
Is there any option in UltraEdit to solve this problem?

Thank you
