TestComplete 9.20: Windows 8 Metro overlaps with the aplication

I use TestComplete/TestExecute 9.20 to test an application on windows 8.



Many a times Testcomplete can't click on button on dialogs appeared on windows 8 slave.

Test log suggest there was an overlapping dialog and the logged picture shows metro desktop"



There is actually nothing overlapping the dialog on slave.



I tried all three options of creating user sessions, manual/RDP/Console. But could not find a solution.



Can you please suggest the best method of creating user session for ditributed testing on windows 8 ?



Any help regarding this problem would be apreciated.
