Hi all.,
Very Briefly just to say:
"Thanks, David."
Working with various display types/drivers etc and maintaining or retrieving
the correct colours has been a bit of a "bete noir" for myself for quite a
while, but now, no longer do I have to physically reset displays to 256
colours when working with TVRD...
Thanks for the tips. Or should that be, to be more respectful, "Expert
Advice!"
Rich.
