Hi Netters,

I'm sure this has been posted about before, but I couldn't remeber the 
solution to the problem, so...

I've been writing a image viewing program for OS/2 2.0 which uses the
palette manager. Its pretty simple at the moment - displays pgm format images
of any size and 'depth' and lets you scroll around the image in a window.

Everything was whoopy (sassi, froody ;-) until I added a menu to the window.
Now when a drop-down menu goes away the portion of the client area obscured
by the menu gets redrawn with an incorrect palette. The only repaint
messages that don't work properly are when the obscuring window uses the
SAVEBITS option (which doesn't actually cause a WM_PAINT message to get
sent, instead the window 'remembers' what is was covering)

So, what do I have to do to insure that SAVEBITS redraws work with the correct
palette entries?

Cheers

Steve
