Start Windows Task Manager and click the Performance tab. Report on the Physical Memory (K) and Commit Charge (K).
Thanks! Sorry for the delay. Here's what I found when I went to visit again.
Physical Memory (K): 261616
Peak Commit Charge (K): 486616
Also at the bottom there was another line, Commit Charge 438M/999M
I do so appreciate your help in this. You know, because this machine is so slow, it took me about 6 minutes just to get the simple information you asked for!
