Hi Eliot,

I use MongoDB and the Problem occurs when the user clicks within its web
browser.
I don't use Native Boost etc. Only lots of Pharo features like Artifact,
Zinc etc.
Yes, sure, I can try with other vms.
I can try to force the bug with a smalltalk script instead of clicking
within the application but the need of mongo db remains.
I will think about how to create a straight forward reproducible case to
you.
You can send the vm to me I will test it.

Regards
Sabine
