SmoothSplashScreen and Mainform focus -Win8-64Bits

I wish to report that TAdvSmoothSplashScreen cannot focus to Mainform problem is back when running on Windows 8-64Bit. The same application does not has the focus problem in XP or Windows 7 32-Bits. I have tried to manually set FocusParentControl to true and could see the Focustimer event triggered simulating left-mouse click however the mainform  still remain not focus until manual mouse click. Any workaround ?
