Never had such things happen to me here.
Is there some program that you can run, get some dump of the machine you use and post it here? so that the people with the problem can do that to see what relations they have.
I'm using chrome (always updating to the latest) and always have at least 10 tabs open at once, plus stuff like msn, skype and all the other crap you generally have running (logmein, hamachi, daemon tools, coretemp etc) and often have stuff like word/excel etc open for long times too. I also have an up time of about 4~5 days a week (put in sleep mode overnight and hibernation when carrying between places - its a laptop). 8 gigs of ram helps a lot I think, cpu's an i7 too.
How often is this happening to other people? Once a day, when posting say 10 posts a day? Nothing like this happens on other forums etc you post on?
What about other themes? Stuff like adblock etc? (I also have quite a lot of extensions installed)
