When a new program gets installed, the item is in the edit menu area, but does not show up in the applications menu. This is fixed if I close my session of xfce and log back in, but it seems unpredictable as to why it happens or when it happens.
I have tried a couple of ways of manually refreshing, neither seems to work.
Additional Information:
If I right click on desktop, under applications the menu entries are there, so its just on the top bar menu.
