I'm experiencing some very strange behaviour with some Add-ins I wrote to make a custom menu (2 different add-ins). They work fine on my PC, but on some of my coworkers' machines, it's installling the add-in fine, but the menu is not visible.
I can only think some other add-in is not allowing custom menus to be visible. I was thinking perhaps other add-ins are conflicting with my add-in. Has anyone experienced this before?
