Has anyone used one of these IBM keyboards before? Not explicitly the moonrune variant, just in general.

I got one and the left trackpoint button doesn't register that well. It "works", but only if I press it right in the middle or press it down with a bit of force. It's a bit annoying to do while navigating. Has anyone else had this same issue? I ask so that I can return it.

I'm referring to the area I have circled with arrows pointing to it for your convenience.
