I was connecting to Internet via wireless; so it could be the same cause.

>>I am connected to the customer server (via VPN and RDT) on another computer (not this one). All of a sudden I am hitting the following problem. I can open any program (e.g. SSMS, NotePad, TaskManger) but I cannot close them. When I click on any program window as if there is an invisible screen that won't allow my mouse clicks to get to the close/open/any button of the program. Even Task Manager is not accessible.

>>What could be cause this? Anything I can do to "unlock" this problem?
>>
>>TIA.
>>
>>UPDATE. I exited from the RDP and then clicked on it again and the problem resolved by itself.
