Michael,

I just found out that it is not the 3 dots (Alt+8 on a mac keyboard) that cause the problem, (which made me wonder since it worked before), but inside that folder there is a folder with 2 spaces in the name: "Gears internal 2" eliminating one of the spaces solves the problem.

I will use underscores in folder names till you solved it, that is very manageable ;-)
