Ghufran,
All you will need to do is look for the Activmanager, in the system tray next to the clock. It is a white box with our logo inside. If you hover over it, it should say "Activmanager." Please right click this icon, and go to the projector tab. Once there, un-check the box that says you want to receive warnings. This should disable that feature for you.
Please let us know if you have any questions, or if this does not work for you.
Thank you,
