Please describe the problem:
After a couple of clicks, the applet suddenly closes the sliding bar and
henceforth the volume cannot be adjusted at all.



Steps to reproduce:
1. Add 'Volume Control Applet' to the panel
2. Click on the Volume Control Applet. A sliding bar to adjust volume will be
displayed.
3. Click a couple of times in the "empty" space of the sliding bar.


Actual results:
After a couple of clicks, the applet suddenly closes the sliding bar and
henceforth the volume cannot be adjusted at all.


Expected results:
The user should adjust the volume.

Does this happen every time?
Yes.

Other information:
The only way is to delete & re add the applet to the panel
