Okay...  So 5300 cannot read Cardbus (?).  I'm exchanging this one anyway.

Is there a way to localize VM?  Like could I designate only the PCMCIA card as virtual memory?  Guessing not...

Because you (I think you) were right.  Classilla is unbearable; but I'm almost positive it's just a RAM issue.  But RAM is nearly impossible to find for the 5300.
