Keyboard problem or is it me?

[Lon More]

CPU is water cooled and running at 37 degrees.
Keyboard is Logitech, but is new and Iīve not spilt anything on it to date.
Itīs weird that despite going back to using jut two fingers the faults still appear.
No problems on the iPad. Maybe Mac products are superior=
Thatīs interesting . American English keyboard selected. Hit the question mark and it prints = Any ideas=
