Doesn't seem to capture the F buttons?

Works great for most of the keyboard buttons but it doesn't seem to capture the F buttons?

Well, thanks for your feedback, I checked it and didn't hit the issue on my computer.

I'm also having this issue. Most keys seem to work but not for the F keys.
I have my extra mouse buttons mapped to F13-24 so that other programs that don't support extra mouse buttons can detect that I'm pressing them. But pressing the actual F keys on my keyboard do nothing also.
