with the screen full of windows, and a window (in this case aisleriot in freecell mode) half at the bottom of the top left desktop area and half in the top of the bottom left area, when I click the mouse on the titlebar (which is obviously in the top left area) E jumps me to the bottom left desktop area and as long as I hold the mouse button down, I can move the window (the bottom of which I can now see) although the mouse is still in the absolute position on the screen that it was at before the desktop flip.
I cannot reproduce this on demand but I've had it happen several times. In addition, I've noticed that it seems (with an absolutely standard out-of-the-box enlightenment configuration) to be correlated with windows sticking below the gnome panel.
FIXED.
