[comp.sys.next] Windows leaving dirt behind

gessel@masada.cs.swarthmore.edu (Daniel Mark Gessel) (03/20/91)

Ok, I just installed 8 80ns SIMMs in my '030 cube. Then I notice the
windows occasionally leaving dirt behind. Looks like a software
problem (2.0), but I hadn't seen anything like it before. Edit also
seems to crash now, probably no relation. I had jumped into the
monitor, using the mon command from the NMI mini monitor (stupidly) to
use the m command and see my new memory, (it was there), so I figured
perhaps I had currupted a file.

I tried booting off a vanilla 2.0 OD, and the problem showed up there.
I rebooted off the OD, and it went away. . . Now it seems gone when I
boot off my hard disk, but I don't see it really being gone.

Anybody seen this before, know of a fix, etc? I don't know if it's
connected to the memory, doubt that it's connected to a currupted file
(since the OD exhibited the same thing), or what.

Any help is appreciated,

Dan

Since you later indicate that it appears to go away, it might be the
memory.  We had some memory here which didn't work very well until it
had "warmed up" - ie, it didn't work unless you let the machine sit
at the monitor for 5 or ten minutes.  I stole it (we didn't need
the machine, it was during the summer and in a lab) and upped "my"
machine to 16M.  Since I was constantly using that machine, it was
always warmed up, and the memory worked fine.  Turning the machine
off overnight brought back the problem again.

Of course, I might be far, far off-base on this.
