Interesting. I have a 32" Widescreen here and when I manually move the splitters between the gamelist and the picture to the left, next time I start MameUI it's back to the far right.
Same with the splitter between the folder list and gamelist. If I move it to the right, on next start it's on the left again.
I have deleted my MameUI.ini and tried from scratch, no change. It's also not write protected and I'm admin on this pc. Also tried to tweak around manually with the numbers behind
but could not find a good setting. It seems there is a borderline how far each splitter can be moved (I guess the numbers indicate pixel offset from the sides?) and when you come across this border it rolls over.
This happens since many versions of MameUI already, not only since 0.164. My resolution is 1920x1200.
I will attach two screenshots. The first one is after I adjusted the splitters, the second one after I restarted MameUI.
Thanks a lot for your assistance! Much appreciated.
