Decline, just opened Bo how to become a common problem solving summary, I am not the purpose of the egg pain-,-
I guess it's too much of a choice to tolerate a little bit of problem, not to solve uncomfortable skinner.
Win8 used for a long time, Upgrade win8.1 After a problem in the last few months, there is a very egg pain, is the Start menu button failure, point out the Start screen (no animation reaction, locked up like), the mouse point to the upper right corner of the lower right also summon charm bar, only through the keyboard win and win+c to activate, And the frequency of this problem is completely unable to grasp, for a long time only by restarting the explorer to temporarily resolve, but can not be cured.
Baidu Google search for a half-day is still dead find solutions, later or Microsoft community inside a cow people found the way to reproduce the bug, in short, because of some unknown reason, the desktop icon dragged to the upper left corner once will cause the taskbar lock can not use the mouse click.
Workaround: Right-click on the Taskbar-Properties-Navigate and remove the "switch between my most recently used apps" option when I point to the upper-left corner. This will not be locked up, of course, there is no switch recently used features, as in the touch mode of the system how the effect is still unknown need equipment to test.
