Adding a Task Due Date via BB Client

When trying to give an existing task a due date, i cannot get the date to save. After entering the due date i want, I’ve tried hitting the enter key, or mousing away from the date. The date remains until i move out of the task to view the project. When i return, the due date has been replaced with “no due date”.
When changing other data, like project name, there have been times where i hit the BB escape key too soon after entering the data. This resulted in the data not being saved to the server, and was remedied by just waiting until the BB data indicators (the little red arrows in the upper right hand corner) have stopped flashing. I’ve tried this with the due date, and it doesn’t work.

You have a “save” button for new tasks, and an “OK” button for comments, why don’t you just add a “save” button for due date?
