Just figured it out... Upgrading to Lion didn't have anything to do with it... it was upgrading my wireless keyboard (which I've regretted buying for quite sometime now lol) after installing Lion that started this. I used a wired keyboard (an ugly black one) and worked just fine. I found it really funny Limewire would only crash after I typed anything in the search box so I experimented with copying and pasting via mouse and worked like a charm. So... I still want to use my Mac wireless keyboard but I'm going to need to downgrade... I think... so I'm going to google on how to do so lol...
