Shutdown, restart menu gone
 

Could someone please give me some advice on Mandrake 9.1 just installed and apparently running great until i try to close down. When I first installed and clicked the logout button I had the option to restert or close down but now all I get is box with Login and Password which only takes me back to the desktop.
The only way to close down is to switch off which then means I have to go through a system check on restart.
Any help appreciated

Does the box say "XFree86.org" on it?

No it just gives me the option to login again

this happens to me too, i just hit halt in the login place...
