May I ask for more information?
What version of Thunderbird and Lightning do you use?
Do you use other extension that might break Lightning?
Do you use the "Save" button or the "Save and Close" button?
Do you have write access to the target calendar?
Do you get any error messages reported in Tools > Error Console when
trying to save the event?
