I ported a program from 1.3 to OS/2 2.0 (i.e. it is a Smalltalk/V PM image
I ported to ST/V PM 2.0) that uses different bitmaps to show objects in 
various windows. To get a fine output, I do not want to have things drawn
that have the background color, I use the ROP_SCR_PAINT option to
copy the bitmap to the window. Under OS/2 1.3 (and ST/V PM 1.4) every things
worked fine but under OS/2 2.0 (and ported ST/V PM 2.0) the bitmaps
are disappeared, NO BITMAPS at all. I played around with the other options,
the bitmaps were drawn but not in the desired way. I need ROP_SCR_PAINT!

I have the german OS/2 2.0 GA with the german SP installed (ET4000 high 
resolution!).

Any hints?
           Markus.

There is a bug in the OS/2 ET4000 driver that makes GpiBitBlt & GpiWcBitBlt
work erroneously.

Solution: #1 Wait until IBM fixes this bug
          #2 Use WinDrawBitmap (which works if you don't do scaling)
