Rated 4 out of 5 stars

I really like this add-on and now I'm trying the Thunderbird 5.0 Beta 1 with Lightning 1.0b4pre and your alpha 5 version, but when I open a e-mail there is a highlighted message that says the e-mail is a calendar update, but it isn't.

I think there is some kind of cached information that must be cleaned because it started to happen soon after I opened a real calendar update sent from the MS Outlook 2010. When I re-start the Thunderbird the message go away but if I open other or the same real "calendar update" the "highlighted message" appears in every e-mail again.

This is a known bug??
