I did a few quick searches and didn't find anything. 
I have problems with only SOME of my function keys, namely F3 (ext view) and F6 (bombardier). 
Obviously I remapped them to keys that DO work, but I am wondering if this is a somewhat common problem with any known resolutions. If not is there a way to help troubleshoot?
The keyboard is a cheap-o G&E, of unknown model. 
Thanks for the help
