I just installed new version 126.96.36.1993 on my Windows 7 Home Premium (x64) system. I do not like the dark theme that is the default. I find a lot of the screen text hard to read. I want a light background. I've searched the forum(s) and did find something that said this could be changed under the "Color and Font branch under Configuration" however that was from 2011 and there is no such choice under Options/Configuration or any of the listings there. I also found some discussions of a tool for themes but that referred to UltraEdit. How can I change this theme? As it stands now UC is almost unusable for me.
You should take a look on the New feature tour for UltraCompare for Windows.
Light themes are Modern Light and Classic selectable in menu View - Themes. A customization of the special theme Classic requires the selection of Custom on tab Application for the Application style.
The Manage Themes dialog lets the user select a theme and preview the look of UltraCompare with the selected theme before applying it permanently. In this dialog also all colors and some fonts can be set if the user wants to create his own UltraCompare theme and also preview them before saving it into the theme file.
As I'm still a fan of Windows 95 desktop theme and have configured my Windows 7 and Windows XP computers to look like Windows 95 as much as possible (Windows Classic theme with no visual effects enabled, color fading in title bars disabled, clear type disabled, mnemonic keys always underlined, no shadows), the UC/UE/UES Classic theme with Windows Classic is the application style I'm using.
