I am running a MacBook Pro, 2.4 GHz Intel Cor 2 Duo, 4GB RAM upgraded to Mountain Lion (10.8.2). Over the last few days, when I click and drag icons on my desktop, the items I dragged will not release. Doesn't matter if I move to Chrome or another program or try to click the trackpad again, the item(s) remains highlighted and acts as if I am still holding down the trackpad trying to find a place to drag it to. (I hope that makes sense). The only way I can fix this is to relaunch the Finder but it only temporarily solves the problem until I click and drag again. So, 2 things: 1. Anyone know how to fix this? 2. If not, I'm thinking of nuking and repaving. I am assuming that I use the install DVDs, then upgrade to Lion, then Mountain Lion through the App Store? Thanks for your help or any suggestions you have.
