Hello, detetected this problem with Free 2.0.1 but went ahead, paid sub for Pro anyway. Uninstalled Free 2.0.1. Upgraded joomla to 2.5.11 first, upgraded Tracktime to latest 2.0.3, plugged in Pro code.
Created Customer, two categories, try to insert project; will not allow Description field to be entered, will not respond to Save, Save and Close, Cancel - no js firing? No error messages to me - escape by navigating to /administrator/index.php.
I tried opening that new project you created, but this time using Internet Explorer instead of Firefox: opens project, but cannot type in the Description box or save /cancel, again. Will go back and try FF again, after restarting PC and send new answer shortly. I had previously (a week ago?) with Free 2.0.1 succeeded.
