anyone have the issue where the physical keyboard seems to stick with the spacebar or the backspace keys? it's not VISUALLY sticking, but after some testing, it seems like if I hit the spacebar in the right place or at the right time or something, it "sticks" and it starts typing a bunch of spaces until i touch another button. Not a huge deal if you're a fast typer, but there have been a few times where i'll finish a sentence, hit the period, then space, and stop to think and look down and there are 100 spaces in a row. I've also noticed it with the backspace key. Haven't tested it with any other keys either. Not sure if it's hardware or software glitch. Anyone else having this??
