Cool. Hard bugs are easier to fix. 
Please write up a mantis report describing 
how one can get to the broken point.

6975: [RFE] Better event distictions between drag, click and mouse up.	


I've updated the relationships to point to earlier (closed) reports I worked on.

There are a bunch of problems (imho) with MouseClickState and its current handler. 
I made an earlier pass at them but did not persue getting the fixes into an image. 
I would be happy to pick up the fight again 
if you provided some ammunition in the form of a Mantis report.

My last efforts did result in a MouseClickExerciser 
which updated Dan's DoubleClickExample to meet current expectations. 
That is now in the image Objects tool under demo. 

I also dabbled in some tools for analyzing click state problems. 
One of my observations is that when waiting for double clicks 
most morphs will lose mouse focus after the first click (mouseup). 
To my mind this will be found to be a culprit for some bug.  
But I don't know which one. 

So describe your problem in enough detail to allow it to be reproduced. 
Start a seed for the issue on mantis and I will see what can be done.

Yours in curiosity and service, --Jerome Peace
