Just got back from 8 months out of country, and when moving my profile from my laptop to my desktop, my Lightning Calendar does not appear on the desktop. Calendar still functions correctly on my laptop, but never appears on the desktop. Both machines running Tbird 68.9.0 and Lightning 68.9.0. Procedure I use is to copy profile folder on my laptop (when Thunderbird is not running), then move that copy to the profile folder of the desktop, rename it to the correct profile file name, and start Thunderbird on the desktop. Can anyone help me get my Lightning Calendar running on the desktop? Thanks, Jeff
