Works Great Rated 5 out of 5 stars

Using XNote on Thunderbird 3.1.5.XNotes is working, but causing Thunderbird to crash when I click Display Message Threads in the inbox view. I have tried this 4 or 5 times and it crashes every time. Has anyone else seen this behavior? If not for this fatal flaw, I would give it 5 stars because it is so useful.
Follow Up: Disabled add on, restarted TBird, enabled add on, restarteded TBird, and it works fine. This is a handy add on.

This review is for a previous version of the add-on (2.2.1). 

Cannot reproduce

Using XNote 2.2.1 on Thunderbird 3.1.5 and cannot reproduce this issue.

Does Thunderbird still crash, if you uninstall all other add-ons? If no, XNote should not be the cause.
Does Thunderbird still crash, if you uninstall all add-ons? If yes, XNote should not be the cause.
This way you could iteratively try to find out which of the add-ons or which combination of add-ons causes the problem.
Can you reproduce the issue with a clean Thunderbird profile? (For this, create a new profile -- see http://kb.mozillazine.org/Profile_manager -- copy the "Mail/Local_Folders/Inbox" file from your old Thunderbird profile to you new profile while Thunderbird is closed, and start up with the new Thunderbird profile.)

Please, don't post the answers (as well as bug reports) here. Rather send me an e-mail -- see http://www.froihofer.net/xnote/ for details. There is no possibility for discussion here.
