I like Microsoft Natural 4000 keyboard but I hate "FLOCK" key. It seems sometimes I push it by accident and then F1-F12 keys stop working.
For Example in Windows Explorer I try to rename file pressing "F2" but instead of that I involve "Undo" action. So instead of renaming files I have created previously just disappear! It's very inconvenient! I never use "Function keys" so can I somehow just have FLOCK enabled?
