In the weekly overview you only have to click once for creating a new event. In the "ganztäglich" field at the top though you have to click twice as well as in the monthly view. Maybe this could all be identical.

Steps to reproduce:

1. Select weekly view.
2. Click on the field in the column of a day you want a create for and that is in the "ganztätig" row.

Actual result:
Nothing happens. Only when you double click the dialogue box for a new event opens.

Expected result:
Same as when clicking anywhere else to create an event, clicking once should open the dialogue box.
