Solid Black box - Hotbar icon size selector

[Nehel]

When I try to change the Icon size on my hot bar it opens up a windo that used to have a Slider and a number window for me to change the size of the hotbar icons. I recently addded 4 - 6 new Ui components that I have used in other UI's before ( all downloaded here). I broke rule number 1 of making a Mix and match ui.... One piece at a time. And now when I try to change hotbar size, the window comes up as a SOLID BLACK window, with no way to close it. If i click on the icon size option again, it opents a Second, antd third.....


Can anyone tell me what hife it is that i need to replace to get that window to work.

Thanks in advance.
