i jus hung up and my desktop is frozen
this is the 2nd time, dun remember the first time
i can swipe to switch desktops, open menu but cant slect widgets or shortcuts
and its frozen coz facebook widget wont scroll
status menu is fine though
and tap to show settings is still ok and i can open the apps from menu
how can i findout what caused this?
i didnt restart my mobile yet and i can use xterm

Have you got desktop command execution widget installed?
That is known to cause this issue..

restart hildon-desktop by typing killall hildon-desktop as root in terminal

thank yous
