Calendar problems

[Lisa186]

I have been experiencing a very annoying problem when I try to open my calendar, and it won´t open. So what I have to resort to doing is logging out and logging back in and then I can access my calendar.

This problem comes up constantly.

 I have the exact same problem, even if I log out and log back in it still will not open the calendar very very frustrating!!
