It happens apparently with any plugin, that needs some calculation time 
and that starts
calculation while the mousepointer is pressed.

I spent a lot of time to find a way to reproduce, because this happens very
often in noisereduction for me, it is disturbing.

Here is a better way and more reasonable way to reproduce:

Move a rubber and hold mouse button down, until the progress bar starts 
running.
While the progressbar is running, release mousebutton and move mousepointer
away quickly.
After this, the mouse is "glued" to the rubber.
This can be reproduced in Noisereduction plugin and in refocus plugin
(make window large enough, so that it is busy for one second).
I believe, that the rubber doesnt catch the "Mousebutton Up" Event, when 
the mouse
is moved away while the plugin is busy calculating.

Because noisereduction parameters need accurate adjustment, and I move the
rubbers slowly, this happens quite often to me.
