My MacBook is only 1-1/2 months old or so, and I dropped it fatally and it broke fairly badly. Needed a new logic board, and one 2GB module out of the two that comprise my 4GB RAM broke.

So, now that I get my laptop back, everything seems to run beautifully and just like it used to, except just about every major program "quit[s] unexpectedly." MS Word 04 does it, Safari definitely does it, and now iTunes does it. I reinstalled my MS Word, and it hasn't done it since (though I haven't had it open for longer than 3 minutes).

I think I read somewhere on these forums that if this happens frequently to an app, you ought to delete the p-list or something like that.

Any suggestions? I'm quite the n00b with any computer--Mac or Windows.
