I expect if it's an U/C skin then you have an error with it somewhere...
U/C skin??, not sure what that is.
here's another hint though: I created another blind a copied over the per pixel frames and buttons. when applied the same thing happens (dead buttons in office, other progs work fine still) but now I have this rectangle across the buttons when I mouse over, which I didn't have before.
top is normal, bottom is mouseover
changed painting margins on the frames and button positions only, no other changes? oh, except I removed the button glow graphics.
but dosent office have issues with wb skins anyway? or is that just a myth?
this is the first time I encountered any skin problems with skinning of the frames all my other blinds work fine???
