Are you on MacOS?  I seem to be suddenly running into strange issues with images after updating to the latest QT - BUM maps (extension changed to .bmp) show flat green.  PNGs show weirdly.  That said, though, Poser uses its own set of libraries (ImageIOPlugins) - so it would need to be even lower than QT (filesystem or worse).

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
