Random Enter Key

I have a Samsung Q1 secondary machine running XP and Multiplicity Pro. When typing it just randomly triggers the enter key when I'm typing. Here's an example.

I never touched the enter key a single time during that passage. I update Multiplicity religiously and this particular machine has always experienced this issue. Anyone ever heard of this?
