The N key toggles snap to grid in its "natural" state.  Try unbinding that key entirely.  It could be some sort of collision.  For most, it's working as expected.  So I'm suspecting a specific setting is causing this for you.  

I can replicate what you folks are seeing if I bind it to "F3". What happens if you unbind the key? It's working properly with "N" for me but not with a second key binding.

Just got off the phone with support and mine is fixed. Here's what the problem was. I had a manual binding of "N" to toggle snap. Evidently, "N" is hard coded as a keyboard shortcut and having it additionally manually mapped (even though it was the same binding) was causing a problem that manifested in the behavior I was seeing.

BTW, the support guy was great (didn't get his name, sadly). Kudos.

The problem has been solved for me, too. It turns out that I had another key binding for toggling snap that I had set up manually for X1. The problem disappeared when I removed that binding.

Since the problem fixed itself for me, and since unbinding keys from "Snap to Grid On/Off" still allows the "n" key to work, I'll go ahead and mark this "solved" (assuming Firefox lets me do it).
