I have two versions of a wine program. Curently, they are named the same. I would like to change their name form "Program name" to "Program name vesion.number".

These programs have their .desktop files in ~.local/share/applications/wine/Programs/.
When I edit them and change the name attribute in the desktop file, nothing happens. (I remove and install leafpad all over to force some cache updating).

When I rename the "Program name.desktop" files to for example "Program nameAAA.desktop", the name in the dash changes. when I rename them back, it reverts to the original.

I can live with "Program nameAAA.desktop" but I still wonder why this happens? I suspect some cache somewhere.
