I had this exact same problem until I un-installed spb backup. I suspect their 'sync backup with PC' feature has some problems, but I don't know for sure. I was having other problems with it so I uninstalled, and this problem (would always connect the way it was last connected regardless of popup setting) went away as a bonus!

So, especially since you don't use spb backup - uninstall it and see if that helps!
