Hi,

Next time it happens, could you create a dump from Visual Studio (from the Debug menu), create a ticket in our bugtracker and attach it so we can debug it? The crash is happening in whichever delegate is attached to that event, not in the notification code directly.

Thanks

I create a Dump file by Debug->Save as dump, and I get a so big file, much to 396MB after zipped. maybe something wrong on my operation? and you bugtracker limit file to 5MB

Try creating a minidump without the heap:
Minidump.PNG
Minidump.PNG (5.05 KiB) Viewed 1190 times
It doesn't have as much information but it will give us something to work with.

Thank you.
