memory problem? registry? i dunno.

As an example, my computer wont remember some things, like it might not keep cookies stored, etc...but i dont think cookies are the problem, because it happens in other programs too, like Thunderbird email (the only one i can think of right now because i'm using it).

What Thunderbird does, is every time i open it, it asks me if I want to use it as my default mail program, and every time I say yes (and i mark the box for it not to ask me again). But of course, it does it every time anyway. Also, it "installs" the same update (1.5.0.12) approximately once per day.

i dont think it's a problem with TB, but a problem with something on my end? im certainly no expert though, thats why i come here.

I use ebay a lot also, and it seems like the same kind of thing happens there sometimes, where it won't remember my settings (that makes me think cookies).
