When importing PNG from file created by i.e. Photoshop, initially it is displayed correctly in the TheIDE image editor. But an attempt to embed this icon as app icon / tray icon displays it incorrectly: opaque pixels are displayed ok, while there's problem semi-transparent ones. This effect is also displayed when you just imported non-opaque image and click "Alpha" tool button. I placed original and spoiled images together to demonstrate:
I assume it is somehow connected with premultiplied format U++ uses by default.
