I get the following error when attempting to access Random, Scattered Disturbed Thoughts or other lengthy threads:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 21701 bytes) in /var/www/showthread.php on line 1275
Is there anything that I need to do differently? I get the same error both at home and at work, one is an older XP machine, the other is a 64 bit Vista. At home I have a satellite connection, at work I have Comcast.
