FIX: You cannot enter full-screen mode on a second instance of the Windows Media Player ActiveX control

Consider the following scenario. You embed the Microsoft Windows Media Player ActiveX control in two separate Web pages. You exit from full-screen mode on the first instance of the control. In this scenario, you cannot enter full-screen mode on the second instance of the control.

Additionally, the full-screen controls and mouse pointer may not correctly hide when you use full-screen mode in Windows Media Player ActiveX control version 10.

This problem occurs because the Windows Media Player ActiveX control does not correctly reset when you exit full-screen mode and you use multiple instances of the control.
