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.

Yes, that makes sense - though I did wonder whether the system might be clever enough to detect whether the specific part of the screen was being written to, rather than any graphics write.

I had seen the clock update whilst a program was running - but that was writing text to "Terminal", not drawing graphics.

In my graphics programs I'd always tried to keep the clock clear - If I'd known it wasn't being updated I'd have had a few more pixels to play with. For example, see

Another useful feature would be to have some way of un-dimming the screen from a program.
