Does xStream support dual screen configurations?
If you’re using a NVIDIA video board, you should select the Span option instead of the Dualview one, or else your target application may behave incorrectly (not possible to select native objects anymore, for instance). If you’re getting a problem not fixed by this solution, you should first try to disable the dual-screen and see if the problem persists. If the problem is indeed caused by the dual-screen mode, you should update your drivers to the latest version available before contacting our technical support.
