Addressee and Subject greyed out Rated 3 out of 5 stars

Lee, you know, I noticed that yesterday but I didn't associate it with Buttons!. I closed TB, reopened it and then carried on editing from Drafts and everything was fine! I'm using TB5, WindowsXP SP3.

Buttons! for Thunderbird 5.0 Rated 5 out of 5 stars

Updating the MaxVersion of the install.rdf file in the xpi package to 5.0 seems to work. I have just reinstalled with this mod and no problems so far.

Rated 5 out of 5 stars

Seems like most developers are way behind with updating their add-ons for Thunderbird 5, and Buttons! is no exception. However, as the extension package format is identical to Firefox, thought I'd give updating the install.rdf file of the xpi package MaxVersion parameter to 5.0 and try installing to see what happened. Seems to work OK!
