they were png..i wonder if that mattered?
Not sure but I think using png/tga is the best way to go whenever possible, better then bitmap with magic pink.
I have a skin I have been playing at for awhile, png buttons (not a complete set) I could not, tried everything I could think of, get buttons to not show up. Had all transparency and translucency off for buttons and caption but buttons were still there.
and my window right uis and left uis would not resize in one of the windows
Are you using uis as per pixel, the way the top, bottom and sides match in per pixel is different than uis. Top is complete imag left to right sides start under it not beside it as in uis skin, bottom is same complete image left to right.
