We were sort of just free chatting while waiting
for you to report something concrete we can try to
analyze ....

If you notice we aren't even 100% sure what you mean
by memory quotas.

Especially now that you say the "system hits a brick wall".

You need to report the exact symptoms and something about
what you see in TaskMgr.

Now, that migh not make it clear -- I know of one program
that SEEMS to cause something that might be described this
way, when it runs the system out of Handles or GDI objects.

(The particular program displays hundreds or thousands
of icons and pictures.)

When the problem occurs, there is memory to spare and no
obvous limit for the objects above is reached but other
programs like Outlook and even Explorer itself will have
trouble opening new windows, etc.
