My PC sometimes gets to an state where double-clicking on an icon will NOT launch the application at all
I have to log out and back in to start seeing windows again .
It shows the sandclock for about the time it takes to launch the application but the GUI is not rendered at all.
When logging off (and progressively killing all applications) the lagging windows magically appear again (I guess after the OS has killed the process that was causing this strange behavior).
Anyone has a clue on what could be causing this?
