I have noticed the following bug when running several programs with various
screens, and with some in interlace; am I alone or do others find this ?

I'm working with, lets say AegisDrawPlus, uEmacs, popCLI,
performance monitor, and the workbench (I have 2.5Meg on a A1000).
Now, I pop the uEmacs screen forward, do a little text action, then pop
it to the back. The highres DrawPlus screen come forward as only it's upper
half, displayed in non-interlace (200lines). It looks like the screen
information got walked on.
If, I only use left-amiga-N to bring the workbench forward everything
lives and keeps running. BUT, if I try to use the mouse to push this
broken screen back, lockup&reboot.

The really bad news is that I've seen this with several different programs,
And also without any uEmacs running.
It almost seems like it's a bug in intuition, since it appears independent
of the exact programs. It seems to be correlated with poping between interlace
and non-interlace screens. If I'm not alone on this, maybe I'll try to get
a specific reproduction of the setup and operations which cause it
reliably. It is a major problem, and makes it hard to depend on the machine
(which I really do depend on these days).
AmigaTeX and it's previewer and uEmacs all together, with the workbench in
interlace and uEmacs not in interlace seems to do it really often.
It was so bad I was forced to make the previewer stay as a window on the
workbench instead of being another screen, and using TxEd, so essentially
everybody is on one screen. Then, since I never pop screens it doesn't happen.

Bummer,
   Ralph
