Has anyone else had the constant problem where the left panel freezes, and you cannot access anything (navigation, transactions, contacts) in it, to include the inability to dock? This happens at least every 30 minutes, sometimes more, and requires a complete restart of the client. I've searched across everything I can think of, but to no avail. Any suggestions (aside from kill the computer, bang head against wall, call my senator, etc) would be appreciated. Cheers!
