Maybe issue with other systems too, not sure. I can click "due date" to make the due date active and the date is then highlighted as though the keyboard will allow it to be edited. However, the keyboard does not actually have the focus there and cannot change the date. It should be that the keyboard focus is active and functional on the date as soon as the checkbox is clicked with the cursor (even though the checkbox being checked via the keyboard would expect the user to hit tab to then edit the date). And the highlight shouldn't happen unless the field is active.
A fix was made and checked into the source code repository of Task Coach. The fix will be part of the next release. You will get another notification when that release is available with the request to install the new release and confirm that your issue has indeed been fixed.
If you like, you can download a recent build from http://www.fraca7.net/TaskCoach-packages/latest_bugfixes.py to test the fix.
Because a fix has been made for this bug report, the priority of this report has been lowered to 1 and its resolution has been set to 'Fixed'.
Thanks, Task Coach development team
