Rated 2 out of 5 stars

Just tested with Thunderbird 3.1.2 on Linux Ubuntu. I have selected 220 of my spam and click to submit them to signal spam.
Then Thunderbird hangs without any indication of progress and a lot of windows with no name opened, has shown in this post: http://www.geckozone.org/forum/viewtopic.php?p=582260#p582260
I am disapointed

This review is for a previous version of the add-on (0.5).
