--- Comment #26 from Christian Uceda christianuceda@yahoo.com --- I forgot to add that this bug does not only prevent drawing, it prevents effective usage of any operation that depends on keeping the left mouse button pressed.
For example selecting stuff is quite hit and miss, and when trying to refine edges in CS5/CS6 this problem breaks the refining process as it makes mouse fine selection almost impossible.
