Grrrr....
I increased my Virtual Memory to 200 MB (plus physical RAM of 64 MB on top), then assigned Outlook Express 150 MB (100 MB min, 150 Max) and still gives me "out of memory" error. I don't think I have as many messages, though, VGZ. But it seems like the amount of memory doesn't matter here...
What a $#%& is going on???? Maybe Virtual Memory doesn't count?
For your information, here's my config:
iMac DV+
64 MB RAM + 200 MB Virtual Memory
30 GB HD (about half available)
Mac OS X + 9.1 + Language Kit installed
Thank you for all of your help.
