I normally have Compiz disabled on my Ubuntu box. However, I decided to enable it so that I could get Windows 7's "[Aero Snap](http://windows.microsoft.com/en-US/windows7/products/features/snap)" functionality. (Instructions on how to get Aero Snap with Compiz are [here](http://www.omgubuntu.co.uk/2009/11/get-aero-snap-in-ubuntu/), for anyone interested.)

I have Ctrl+1 through Ctrl+4 hotkeyed to switch to different workspaces, or viewports as Compiz calls them. With Compiz disabled I was able to move a window to a different workspace by grabbing it (clicking and holding on its title bar) and then pressing the appropriate hotkey. Since enabling Compiz, I can no longer do so.

Is there any way to get that functionality back? I much prefer it to having to right click the window's title bar and choose from the "Move to Another Workspace" menu.
