I have the same problem, with more complexities. From agenda, checking calendar selector in the view menu usually allows me to get out of agenda, sometimes I will also have to check sidebar or something else. But eventually, if I change views I will get either a blank widow instead of a calendar, or the program will close. Is agenda just unstable? It seems as if I pass through it on the way to crashing. Is there a particular setup that avoids these problems?
Thank you if you have any ideas
