When I go to the task bar/notification area, and click the up arrow, to show hidden icons, the menu opens, and (shivers?) I don't really know how else to explain it. It just jerks back and forth, so bad that I can not click on any icon. Really, I barely can tell which icon is which. Any body else had this problem? If so how did you fix it? Although, the way things have been going, in a day or two it will fix itself.
