Although we have moved to flwm_topside, Refresh_Menu still wants to call flwm_restart.
I tried using flwm_topside_restart, but it also refers to flwm.
[Edit]
And trying "kill -s USR2 `pidof flwm_topside`" doesn't refresh the menu either.
This is related to the issue of menu entries that are added to the tce.menu folder but don't get displayed.
It takes a full restart of X to refresh the menus.
