What I mean is this area on the left side of the green line
accessible when the pointer turns to this double arr-owed icon visible on this image
I am using a resolution bigger than 1080p and an ordinary office mouse with low DPI. And for me catching the side of the Tag Panel, so that I can adjust it, is simply difficult: sometime I go back and forth, few pixels to the left an then to the right, till I finally have the pointer changed [indicating that I can grab my Tag Panel]
I tried changing settings in my Windows 7 x64 under the
Control Panel > Appearance and Personalization > Personalization > Window Color and Appearance > Advanced appearance settings...but it did not help even a bit
The divider between the Window parts is governed by Windows - so there is probably very little chance unless MP3tag invents the graphic user interface anew.
You can set the window border thickness - but that is probably not what you are looking for.
If the mouse causes you discomfort, perhaps a track ball helps you to position the mouse cursor easier.
You are probably right. I have similar problem with FreeCommander and its splitter between two main windows
The problem is the surface + low end wireless mouse + high resolution
Surface cannot be changed as it both functions as an office desk and a worktable; big bucks I would spend on a gaming mouse, but then I wouldn't use it for office work; high resolution I need for my non-musical work on my big monitor
And the wireless trackball is something that I want to check out since the last decade
