type="cite"><PRE wrap="">This is in no way a PostGIS problem, certainly nothing we can ever
fix, just something that the particular combination of PgAdmin, the
geometry we are feeding it, and the way the Windows rendering system
are interacting.
My experience has been that these days the thing that causes a modern
operating system (Windows, Linux, whatever) to crash is bad hardware,
usually bad memory, but sometimes other things. Basically, the
operating system itself is usually rock solid until you shake the
foundations it sits on, the hardware.
So basically, all I can offer is the doctor's advice to the patient
who said "doctor, doctor, it hurts when I raise my arm over my
head!"... "don't raise your arm over your head".
In the meantime, if you want to fiddle with things, swapping the order
of your memory in the sockets, changing out the video card, even
changing your screen resolution, might change the interaction such
that you can exercise this particular use case without dropping your
OS to the floor.

<BLOCKQUOTE type="cite"><PRE wrap="">I second Bruce's comment about unhelpful comments.
It may actually have nothing to do with Windows in fact.
Now getting back to the crash issue. Bob if you are still having the same
issue with that file, maybe you can post that (or provide a link to the
shape file you loaded). It could be something to do with the shapefile.
I recall having this same issue with one particular geometry file way back
in PgAdmin 1.6 and it was when I scrolled to a specific record it would
crash, but then later additions (I either maybe never selected the geometry
field again) or it was fixed in later versions. Doing an AsText
always seemed to work where as displaying the raw binary was where I ran
into issues.
The other possibility is that it could be a defective graphics card. I
forget which video cards I had bad runs with, but I remember having this
same exact issue with my favorite programming editor JEdit. I had 2
identical computers with same drivers etc and for some reason I would get
intermittent crashes on one of them. I finally just got fed up and replaced
the graphics card and then it worked fine.
Just some thoughts.
Thanks,
Regina
