[X4U] Processor Maxes out

[Chuck McDonald]

Quite often when I check mail with Mail.app or download web pages  
with Safari, those applications will max out the cpu to about 80%. I  
have rebuilt mailboxes, reset Safari, emptied the caches, and the  
problem is still there. It is so bad that Safari appears to hang  
because it is using so much of the processor. I have an imac 2 GHz  
with 1.5 MB of ram. Any suggestions?
