When I go to the calendar and add a new event. The event dialog takes up the whole screen and sometimes goes off the screen, especially on smaller displays. It would look much better is the new event dialog was much smaller, just like the new task dialog. The size of the dialogs could be reduced by making the text smaller. The text size is quite big and doesn't need to be.

Also the top bar on new task and new event just over the name is grey and looks really odd.
