not properly wok compiz function "Put to arbitrary viewport" from plugin "Put" (/usr/lib/compiz/libput.so).

Binary package hint: compiz-plugins-main

(sorry for my English)
On my laptop with Ubuntu 11.04 (Natty) when I use hot keys in compiz for make "Put to arbitrary viewport" (compiz plugin "Put", library /usr/lib/compiz/libput.so), I can't move windows to all viewports (virtual desktops). After login into gnome session I can make only one correct movement window to viewport. After that all windows moving to the same viewport even when I specifying another viewport (pressing another hot key).

Before upgrade from Maverick to Natty this movement worked good.
