| Tracker won't release on Mouse-up [message #520449] |

I'm having an intermittent problem with Tracker in that 25% of the time it does not release the rubber-band box when I let go of the mouse button. Most of the time this works as it should, but I have not found a pattern or correlation of when it works versus when it doesn't. It appears to be a bug.
The usual and expected behavior is: when I press and hold down Button 1, and move the mouse, the Tracker box follows the mouse. When I release Button 1, the box stops following the mouse movements.
But when this fails, what happens is the Tracker box continues to follow the mouse movements even after I release Button 1 (as if Tracker was unaware that Button 1 has been released). Sometimes, it takes several clicks of Button 1 to cause the Tracker box to let go.
Has anyone else had this problem? Any ideas of what I could do to work around the problem? My code pretty much just mimics the Tracker sample code provided by Eclipse...
thanks for the help!

Hi Mark,
Tracker should be reasonably straight-forward, so as you say, you're
probably seeing a bug. Which platform and SWT version are you using? Do
you see the problem with
http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org. eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet23. java ?

I am not having the same problem with Snippet23. However, I am no longer having the problem with my code either. I am simply not able to repeat the problem today even though other times the problem occurs more than 50% of the time. So there must be some external factors that influence this, say a load on the system, etc.. Perhaps I should wait until the problem occurs again in my code and then try out Snippet23 again to see if it happens there as well...
I don't think this issue simply fixed itself, but rather is not revealing itself today. I'll post again if it does to discuss whether a bug report is needed...
