I have a big problem with the ADMS 2012 Management Console at the moment. When I open the application, I get the login dialog OK, but then the app just minimizes to the task bar, and sits there. Any help would be greatly appreciated.
Are you able to select it in the task bar and use the Windows + right (or left) arrow to "snap" it to the side of the screen?

I think what Andy is alluding to is that the console window might be off screen. Have you used a dual monitor setup and/or changed your screen resolution lately?

If after you login to the ADMS console, and it minimizes to the taskbar, can you RMB and select Restore or Maximize?
