Hi folks,
Ctrl+Alt+Esc should bring up the task manager. If you're seeing behavior resulting in a minimized application, you're probably pressing Alt+Esc, or the Ctrl isn't being recognized, which is what happens to me when I try and use ^!{ESC}.
In my case, a customer is opening a 3rd party remote control application (think VNC), but sometimes the Ctrl+Alt+Del screen is presented when the machine isn't already logged on. Ctrl+Alt+Esc is the keyboard shortcut to "send" a Ctrl+Alt+Del through the app according to the makers of the app. I find it a bit odd that they didn't choose some other unused combination of keys to trigger that action within their software, but that's another story.
So, we're definitely not looking to minimize a screen, and we're definitely not trying to pass a Ctrl+Alt+Del.
Thanks everyone for your replies (even those that thought this was about Ctrl+Alt+Del ).
