janosdelaromani, you need to update to the latest ProfitUI version.
There is now a
thread on EQ2players.com concerning this issue. A tech support person from SOE repsonded. So they are atleast aware. Whether they will fix it soon, we can only see.
I played around with this for a couple more hours since my last post. I completely removed every ProfitUI file and redownloaded. At the same time, I deleted my character's uisettings file and used the default ProfitUI 1280x1024 file. I opened the boxes one at a time. By moving each one over to the left of the screen after I opened it, then opening the next, it seemed to work better. It seems that any time they started bunching up to the right, those slot's windows would become permanently "ruined" (wouldn't save setting). I would have to delete the character settings file and do it again. By doing this VERY carefully, I was able to get it to only ruin the 12th personal bank slot. Even tho I was very careful with this window also, it still got ruined. Trying it again... backward... I got it to only ruin slot number 9. It still would always ruin atleast one of the windows.
Eh, for now I guess I'll just not use all bank slots. It really annoys me to not have my inventory windows stay where I put them, so I'd rather just not use the one that is ruined.
