I ran the below code with no problems. Maybe try a try a loop with WinActive that calls the next window until successful. #include <IE.au3>
Local $dropTask = _IECreate("www.google.com/")
Local $focusSupportPage = _IECreate("www.msn.com/")
WinSetState($dropTask.HWND,"", @SW_Minimize)
WinSetState($focusSupportPage.HWND,"", @SW_Minimize)
While 1
While Not(WinGetState($dropTask.HWND) = 47)
WinSetState($dropTask.HWND,"", @SW_Maximize)
WinActivate($dropTask)
WEnd
Send("{f11}"); full screen
Sleep(10000)
Send("{f11}"); full screen
WinSetState($dropTask.HWND,"", @SW_Minimize)
While Not(WinGetState($focusSupportPage.HWND) = 47)
WinSetState($focusSupportPage.HWND,"", @SW_Maximize)
WinActivate($focusSupportPage)
WEnd
Send("{f11}"); full screen
Sleep(10000)
Send("{f11}"); full screen
WinSetState($focusSupportPage.HWND,"", @SW_Minimize)
WEnd
