(Thunderbird :: Message Compose Window, defect)

I upgraded to the current version of Thunderbird offered at your website and now the compose email window fails to respond to mouse clicks on any of the navigation buttons such as 'attach', 'send', 'save' etc.  To advance from 'send to' line in header, I have to press return (twice) to advance to subject line.  From the subject line I can get to the body of the message normally.   Once in the body area, I can't return to the 'send to' or 'subject' line elements, nor can I use any of the navigation buttons.
Using the main menu bar does allow me to eventually send or attach, etc.

Reproducible: Always

Steps to Reproduce:
1. Open or 'reply' or 'forward' any message
2. Type sender's name (you'll notice you must hit return twice to advance)
3. Type subject line (advances normally to body of message)
4. Type as normal
5. Try to get anywhere using navigation buttons or mouse clicking... 

Actual Results:  
Unable to activate any buttons to save, send, etc.  Also, unable to click back into subject line or sender line to make changes.

Expected Results:  
Normally navigation buttons should work according to their descriptions and one should be able to navigate anywhere in the message compose window using their mouse.

No crashes (yet), no themes, nothing special about this Mac in terms of configuration. I'm just a simple user that loved the previous incarnation of Thunderbird... but have yet to love this one. :)
