Created attachment 147382 [details] what the "New Event" window looks like just after clicking the "Ok" button SUMMARY KOrganizer periodically stops allowing me to add new events to my calendar. Nothing I have tried seems to allow a new event to go through to my calendar while this bug is active. I have attached a screenshot of what the "New Event" window looks like just after clicking the "Ok" button. STEPS TO REPRODUCE 1. Don't restart your computer for a few days. 2. Open the "New Event" window and fill in any info whatsoever for the event details. 3. Click "Ok" or "Apply". OBSERVED RESULT The Ok and Apply buttons become gray and un-clickable and the "Calendar:" drop down menu becomes highlighted. My calendar remains unchanged, it does not have the event I just created in it. There are no error messages. There is no way to continue from this point, the window has to be closed by cancelling edits. EXPECTED RESULT That the "New Event" window would close and the event I just filled in the details for would be created and saved to my personal calendar.
