Hello, is there a bug tracker for CalDAVzap anywhere? For better readability I defined a minimum font size within Firefox. If using something greater than 14 pt a display error occurs when defining a new event. The event will be created with a time shift and it will last longer compared to the selected time range. For reproducing try: - define a minimum font size of 20 pt - create a new event by selecting 9:00 with the mouse and pulling it down to 11:00 -> the event will be created from 12:00 to 15:30. I observed this not only with Firefox but with Google Chrome too. Ingo
