[comp.sys.apollo] Gpr direct mode vs. screen timeouts

dente@els.ee.man.ac.uk (Colin Dente) (08/28/90)

Wot? no - it can't be...  yep! 'fraid so... I've been *programming* <gasp>

Now, this wouldn't be so bad - in fact, my program works, and I can even
handle drawing piccys in a partially obscured window!

My problem is: (getting serious now...) I've got a program running in
gpr_$direct mode in a pad which draw lines & stuff every so often.
This is fine, except, when the screen times out, the display flashes
momentarily to life every time my program draws something, instead of
staying blacked out as I'd expect it to.  My question is simple:  How
do I stop it doing this?

Oh yeah - it's a DN330 (3Mb) running SR9.7.5

Cheers

Colin
