I have the same problem, every other function key seems to work fine, except F5. The key works, it not a hardware problem. I closed all other programs to make sure something else wasn't set to use F5. OS X uses F5 for voice over, but I do not have that selected.

Anyone have any ideas? Not a big issue, but a bit annoying.

(I emailed tech support yesterday, haven't heard back yet.
