This sounds very much like the behavior of Protel and a couple of other 
applications under Win95 with low resources. My standard defenses, which have 
pretty much eliminated this problem:

1) Restart Protel periodically.

2) Reboot the system about once per day.

3) Add RSRCMTR.EXE to the Startup menu so that it's always running.

4) Avoid running certain obscure consumer applications at the same time as 
Protel.

Note that none of the above prevent me from running other mainstream 
applications with Protel. I often run Protel with a couple of Word documents 
open, an Excel spreadsheet or two, AOL open and online, Adobe Acrobat Reader 
with a couple of documents open, WinZip, a couple of Explorer windows, and a 
couple of other specialty applications. But anything which makes heavy 
demands on the Resource memory pool (limited in size regardless of the amount 
of physical memory) will cause conflicts with Protel.
