Search for “IE7 memory leak” or “hog” or “problems” and you will see *MANY* people complaining about this, and no solution posted. Run IE7 for a few hours and memory consumption (e.g. Mem Usage and VM Size columns in task m,anager) starts going up to 100s of MB, can get to GB in less than a day. Regardless if you had many tabs, what exactly you were doing, or even idle overnight etc. So I’m forced to kill my IE windows and restart them daily, very annoying for obvious reasons. In my desperation I even considered going to IE8 beta, but read that its memory consumption is much higher!

Now I did read that Firefox has similar problem (even in ver 3), though it might be a different problem. Maybe this has to do with Ajax or Flash or whatever. In any case, a solution is needed, Shame on MS for not doing anything!
