With the 5.50.021 release, my Logoff & Shutdown dialog backgrounds are no longer displaying with proper transparency - the transparent bits are black. The regular Logoff & Shutdown dialog backgrounds use the same .tga as the PPx backgrounds. The Please Wait PPx dialog displays correctly (& has a translucency switch). No way in SKS to influence the painting of the others - the PPx sections would use transparency & translucency by default I'd think.
