Once the Thunderbird window is closed or 'Quit' Thunderbird I need to choose any cmd key from a pulldown menu to reactivate the cmd key control. I'm still running OS 10.5.8 on my Mac. Is this an issue with the Thunderbird 'cmd' key shortcuts? Reproducible: Always Steps to Reproduce: 1.Select 'cmd+' to zoom in to a message body. Nothing happens. 2.Select View>Zoom>Zoom In 'cmd+'. Text size increases. 3. Actual Results: This only works until the Thunderbird window is closed or 'Quit' Thunderbird. To reactivate the 'cmd' key shortcuts I need to choose any cmd key from a pulldown menu. Expected Results: The 'cmd' key shortcuts should response as they did in the previous version of Thunderbird (2.x).

uninstall lightning and things will work.

I uninstalled Lightening 1.0 and installed Google Calendar to replace Lightening. Used Thunderbird less than one hour after installation, all functions appear to be working.
