Comment 3 for bug 788240

Remarkably, this behaviour has changed a lot and for the better after a recent update (this week?).
 I assume that means I'm benefiting from backports. I don't have handy a system with the initial 11.04 distribution, but I think a lot of problems I've reported have been helped (without assignment from my bugs) since then. (It would sort of be nice to have launchpad reflect the real perfomance with which the distro went out, though --- presumably not everyone can update as easily).

So, if I drag a maximised window from my top screen to my bottom screen, it now jumps to maximised as it should (didn't before).
If I alt-f10 a window currently in bottom, it jumps to max in bottom, as it should (didn't before).
If I drag a window so that mouse is in top bar of bottom screen, I think I get a max state in bottom screen too, though I find it very difficult if the window is coming from the top screen (unmaximised).

There is still a problem with the bottom screen max state, though: the top bar of the window is missing/invisible (ie, behind the unity panel there). It remains visible and working properly when max'd in the top screen.
For instance, in Chrome, the tabs are invisible in the bottom max state. This problem exists for other apps too.
