Hi,
I have 1GB of PC3200 RAM and I have set the virtual memory
to between 50 and 500MB. sometimes I get a windows popup
saying that there is not enough virtual memory but when I
check it is only using about 180MB of virtual memory and
~240MB of real memory. How can I stop this annoying
message from appearing - should I pay attention to it or
just ignore it?

Thanks
 
set your virtual memory to be Windows managed.

Hi;
When you're checking it is not the same as when windows is needing it. It
locks up doesn't it!
Don't fiddle and reset to automatic for a while.
Use the built-in utilility to view the actual usage over a good lenght of
time.
....and if you really "must" then give it manually a 50-100% fixed overhead.

thanks all - the reason that I had set the virtual memory
as low is because I didn't think it would be needed
considering how much physical memory I have - the only
reason I have any virtual memory at all is because some of
my programs will not run unless it is present

Classic misunderstanding of how VM is used in modern demand paged Operating
Systems. The OS will page stuff out anyway, because it can use the physical
RAM for things like I/O buffer cache rather than as a place to store
infrequently used stale pages. So having a lot of physical RAM doesn't get
rid of paging and doesn't obviate the need for page files.

Virtual memory is a complex topic.
