ICQ is still giving me fits. I have my old DB files, I have like 3 versions of the ICQ installer...but I can't get it to import my old contact list. I still refuse to enter my contacts by hand though...
There's a really nifty ICQ replacement program called Miranda, and I now use it. It imported my contacts (which the real ICQ still refused to do), it's fast, and it doesn't take much memory. My favorite "feature" is the way it was 200K to download, instead of the 5 megs ICW takes. Modems still suck.
