Hello,  I've been testing this by using the above method to re-enable shake. Here is what I found. Windows "Snap" needs to be enabled for Shake to work. Seamless Windows break if you Snap them. Eg, if you drag the Window to the top of the screen, windows Snap tries to maximise it and it breaks the seamless window control. Quest have disabled snap on purpose to stop seamless windows breaking all the time.  So, snap is disabled on purpose and the side effect of this is that shake gets disabled. It might be worth having a look at MS to see if there is a way to keep shake alive when snap is disabled.    Thanks, Andrew.
Hi, When we run appportal application and run one seamless window app, we are unable to use aero efects on windows 7 desktop like shake windows to minimise all, docking to left/right side... This is valid for all running apps, not only for seamless window which I know is not supported to use aero glas efects Is this by design?  /R.
