I am using Linux Mint 14 (MATE) with Cinnamon installed.
Cinnamon failed when I tried to delete an item on the menu with menu editor.
The system freezed, so I logged out by pressing ctrl+alt+del.
When I logged back in, the desktop panel was not loaded (shortcuts were there as normal, right click works as well). I can barely do anyting but get the terminal with ctrl+alt+t. But all the dialogue windows are presented without any frames.
Here are the screenshots (I have no enough reputation to post image here, sorry):

I tried reinstalling cinnamon in the MATE desktop interface (it works fine) but failed to solve the problem.
Thanks
