A Windows problem, some icons disappear, not only the BoincTasks icon.
This is mostly a serious crash, that is solved by a sort of reboot of the explorer. And the explorer is a lot including the desktop.
There shouldn't be a crash in the first place.

I get this on occasion too...I know that when certain icons don't reappear after a restart of explorer, it is time to restart the machine.  (I'm sure that running several alpha/beta Boinc projects has nothing to do with this  )
