IE7 and the memory hole

Who all has the problem with IE7 and the memory hole? FireFox had this same issue with me and it was one of the main problems of me ending my use with it. But it was a better than IE7s hole. I keep waiting for an update to fix this problem yet it hasn't came yet.

See I'm one of those people that never turn off their machine and I have lots and LOTS of pages open at all times. I'm talking about 20+ at all times however when I hit a certain limit right click stops working I have to close a page or two and it works again for a moment. This is very irritating too me....Then when when the bug finally sets in I can't right click anywhere and this means on the desktop as well. I have to open up task manager and manually shut IE7 down to get the machine working right again. Taking a look at the memory use I see that its eating up 500+ megs and sometimes in more than one spot. It doest matter if I close a page or too or even close IE7 the right way. The high memory use is still there and it so reminds me of windows 98 and not letting go. Now I can imagine people out there that would not know how too do that and having to reset their machine when this happens to them.

Is it better in Vista than in XP???? I like IE7 almost better than FireFox in a ways its just this bug.
