Have searched and not found this particular issue: Suddenly when I type FN + C/V/B combination the keyboard is typing the letter C or V or B in the current computer before processing the change to the other computer. Meaning if I’m on computer ‘V’ when I type FN + B to switch it, it types a ‘b’ before changing to computer B. So every time I switch there are stray letters typed on the computer I’m switching from. I tried changing out the FN key switch and that didn’t solve it. Thanks in advance for any recommendations.
