Question for HP guys about screen updates...

[webmasterpdx]

If you are running a program it can't update, as your program could be drawing up there, and an update would write over your screen.
Obviously somewhere in the system software, when a program starts, it disables updating the screen. When the program stops, it re-enables updating the screen.
I just want to be able to enable it while a program is running...maybe by telling us the call to reenable it.
