Oh, and for those who want me to switch to Linux or Mac, you can go jump in a lake and take your computer with ya, cuz those OS's are just too weird to switch to. I plan to upgrade my computer some time around the holidays this year, but in the mean time, my wife's computer, which has LESS RAM and a SMALLER hard drive, but all the same stuff from the same manufacturer - her father - is twice as fast as mine. I have not changed anything except the occasional Firefox update and Win7 update. IDK what caused it to end before or what exactly caused it to start up again. I will note that this problem only re-surged to an every-few-minutes occurrence with the latest forced Win7 SP update. I have tried setting Firefox to HIGH priority in Task manager, but that only shortens the NOT RESPONDING bug from 2 minutes down to a few seconds. Even while typing this comment I have experienced Firefox going into NOT RESPONDING mode for over 2 minutes without any option except to wait or reboot the browser by crashing it forcefully from Task manager. UPDATE: after finally not having the 'NOT RESPONDING' problem for several months, suddenly it is BACK with a vengeance.
