A while ago I started to get the error messages "Out of memory or system
resources". Close some windows or programs and try again" when pasting
things into Outlook. First this appeared only occasional, but recently
this is showing up practically every time I paste something into
Outlook.

Since I have a machine with 2GB of RAM and ample space for the pagefile
(which I haven't maxed but have it "managed automatically", so it could
grow to whatever the system considers required) and since my .pst file
is down to 65MB (it has been 100MB several times in the past), I don't
think this is really a memory issue. Rather I suspect, that some other
system setting (GDI, icon-cache, or something of that sort) is
overflowing.

Any idea or hint what could cause that problem? Or how to diagnose this?
