Please describe the problem:
Whenever a task is set completed, a tiny clock animation is shown to the right of that task. In case I immediately select the due date combo of any other task and do not close it (i.e. select a date from it) until the animation has finished, the combo turns grey (no content), remains on the desktop, and Tasque freezes.

Steps to reproduce:
1. Select the "completed" box of a task;
2. select the due date combo box of another task, but do not select a date from it;
3. wait until the animation of the task from step 1 finishes.


Actual results:
(See above: Tasque freezes)

Expected results:
Actually, I'd expect the combo to work as normal, i.e. let me select a due date even after the animation has finished.  :)

Does this happen every time?
Yes.
