I have some trouble with the palette manager of OS/2 PM.

1. I load the bitmap in a memory device context and then use 
   WinDrawBitmap to paint it on the screen. The realization of
   the palette works fine and WinDrawBitmap also works fine as
   long as the bitmap gets scaled. If it is painted with 100% size,
   the colors are completely wrong. The same happens with
   GpiBitBlt. Any ideas what's wrong here?
2. When I pop up a menu or a dialog box over a picture with a
   realized palette and then remove it, PM tries to restore the 
   bits under the removed menu by itself and doesn't send me a 
   WM_PAINT message. The problem is, PM doesn't get the colors
   of this repainted area right. This looks like a PM bug to me.

I apprechiate any ideas very much.

Regards, Martin Erzberger
