Scenario: I leave my desk. I hit Ctrl-Alt-Backspace to lock the secondary PC. I hit Ctrl-Alt-Del to lock the Primary PC. I go to a meeting or something.
Come back, hit Ctrl-Alt-Del unlock the Primary. Move the mouse to the secondary PC hit Ctrl-Alt-Backspace and the login box comes up, but I can't type. I can move my mouse, I can Tab around the boxes, I can turns the CAPS lock on and off, and I can hit enter. But I can't type in my password either from the Primary keyboard or the secondary keyboard.
NOTE: I am still using the trial version of the product, but I'm only on my 2nd day. I am stronly considering buying several copies for some employees, but rebooting the secondary PC after being gone for a few minutes is a major hassle.
Hopefully someone has seen this, or at least the devs are working on it.
