Stoffe, perhaps you can help me troubleshoot the behavior....
The settings are being written to a file called kgff.ini which is stored in your %WINDIR% folder.
Launch KGFF, resize the pane and close it.
Then open up kgff.ini in notepad.
Next, Launch KGFF again, do nothing and close it.
Then open up kgff.ini in another notepad.
Compare the two settings. I think they will have changed, and hopefully if they change the same amount each time for you, I can make an adjustment for WinXP users.
