Lightning in Thunderbird unresponsive-stuck in Day frame.

Have Opensuse 12.3 on a older P4 HP Compaq. Installed Thunderbird 17 and Lightning calendar.
When I use the .DEFAULT file which TB creates locally, Lightning works.
When I share a .DEFAULT profile with TB in Ubuntu, Lightning shows the daily frame but does not respond to any mouse clicks.
Am a fairly new Linux user so please be specific with commands or directions.
Thank you
