I'm building a very similar function to the one described by Ben, but
using PowerPoint -- I have an overlay window that is supposed to show
auxiliary info during a PowerPoint presentation. I've verified that
the drawing routines are running on my overlay window, but the updates
are never shown on the screen (I assume because PowerPoint captures
the display). From other postings it seems to be that there is no way
to promote the redrawn state of the overlay window to the screen until
the app releases the display, yes? Are there any known workarounds
for this?
Thanks,
Greg
