Skype Toolbar [what's that?] keeps crashing when I have a number of tabs open in Google Chrome. Each open tab will get this message and my whole system - everything - slows to a crawl unless I go to each tab to close the message. Sometimes I have to close Google Chrome and restart it, losing all my open tabs. What is Skype Toolbar? How do I stop it from crashing all over the place? Any permanent fixes?
