[newbie] disappearing menu items

[Syamsul Anwar]

After I'd installed the Codeweavers' Wine release, menu items were 
created in KDE. But after I'd rebooted, the menu items disappeared! The 
same thing happened with installs of StarOffice and (trial version of) 
Applixware. Darn inconvenient hunting down the install locations to 
create links to the executables. :P 
Any idea what's happening here?
