Roger Whitcomb updated PIVOT-927:
---------------------------------
Attachment: pivot-wtk-2.0.4.jar
Here is an updated 2.0.4 .jar file with the changes to ApplicationContext to
protect against NPE with mouse locations. Hopefully this will be enough for
you to test with. Let me know if you need some other .jar files to go along
with it.

> After mentioned exception occurs user is unable to use any element of UI.
> Only application restart helps solve this problem. Even more confusing is
> fact that problem sometimes occurs after few minutes and sometimes after few
> hours or even days.
> Can anybody give me some pointers how to workaround / fix this situation?
