Jean,
The full name (in Excel XP) is persnlk.xls, but it might well be that it is only operational in a networked environment (as it is here on my work). Anyway, it's not likely to be the cause if the problem occurs at exit.
There seem two obvious (if unpleasant) workarounds:
- Only minimize the program, never exit it.
- Use taskmanager to kill it, never exit it.
I searched on google with excel "System resources dangerously low" which gave about thirty hits on the web, and 7 in the discussion groups. I remember reading one of them, that was about this error occurring when printing a spreadsheet, but I didn't concentrate on this message on exit. That's a very strange place, by the way.
You might try to repeat the search, and read through all hits. It might be helpful.
And, of course, are you sure you're free from malware? Use housecall.antivirus.com (online virus check), spybot and adaware to check. It's a remote possibility, but certainly won't harm.
That's all I have to offer to you regarding this problem.
