I am running Debian testing, and upgraded my packages.  In a recent update, the
ability to drag a window from the Activity area (ie the slightly shrunken view
of all the windows in the current workspace) to a different workspace.

All that happens now is that I release the mouse hovering over the new workspace
and the window flies back to its current position on the existing workspace.

I run two screens, with the second screen being visible from all workspaces.  I
CAN drag from the activity window where there are several workspaces to the
single workspace on the other screen.  I CANNOT drag it back again.

I wasn't 100% sure I had lost that functionality, but I checked the gnome user
guide and I should be able to.
