Hello, sorry for my bad English but I'll try my best.
This is a very useful plugin. But after i activated the calender there appears a problem in my dashboard.
Normally on mouse over there pops out the submenu in the admin navigation.
E.g. Dashboard - pop out: Home, Updates etc.
After activation: no pop out. And i also can't sort the Dashboard anymore. I can't move oder open/ close (small triangle) any plugins.
I hope you understand what i mean. In not: wer kann das bitte ins Englische übersetzen.
