I upgraded my system to 640MB of RAM from 256 and this problem is back in
spades. It occurs faster(30 min. or so) now and seems to occur most often
after I switch accounts. I am getting hangs on the first IE7 tab too. I am
giving my computer the three fingered salute quite often to kill OE6 and IE7
and then restart them. A friend said he had to switch to Firefox and
Thunderbird to use his computer. I tested the new RAM with Dell Bios
Diagnostics and MemTest.
