I have a few items in the Menu that refer to the start scripts of extracted Java programs that came as tarballs.

Go into the Menu Editor and rename one of these (e.g. to reflect an updated version)
Save - Message says "Updating System Configuration"
Browse using Lancelot - the old name is not there but the new one is.
Search using Lancelot - the new name is not there but the old one is.

The new name is only in the search after reboot.

Is there anyway to get Lancelot to update the search index straight away after a menu editor change?
