I believe the XFCE version of Linux Mint was trying to be like the Cinnamon version with a simple press of the Super (Start) key opening the menu. Unfortunately, this conflicts with any other keyboard shortcuts that use the Super key (for example, "xfce4-display-settings" uses Super+P out of the box).

Compiz may introduce more complications.
I developed a workaround involving ksuperkey, but I don't think this will be beginner-friendly.
