> Hi,
> I have been wrestling with a issue with GlobalWindows. It seems like it leaks instances
of InternalTimer.
> I can't tell if it's a bug or my code so I created a 'minimal' project that has the issue...
> If you run the Unit Test  in the attached and then monitor heap you will see that the
number of InternalTimers continually increases. I added code to explicitly delete them.. doesn't
seem to help.
> If I comment out registerEventTimeTimer ... no leak :)
> My suspicion is that PURGE/FIRE_AND_PURGE is leaving the timer in limbo.
> Steve
