Here a patch that is lying around here for quite a while that I use to
prevent an Eudora 4/5 crash with the same symptoms. I wonder if it
helps you.
And yes, GetCurrentObject(..,OBJ_BITMAP) on a freshly created dc
returns != 0 in windows. I'm just not sure this patch is the real
solution, although I haven't seen any negative effects.
