Hi Guys I have an iMac07 running on windows XP since new. Been working fine till a couple of days ago when i lost control of all the function buttons (ie no vol up/down, brightness etc) and no eject. I noticed the IR remote control volume function stopped working too. I have been toying with airplay on itunes lately as i got a pioneer network speaker. I went to bootcamp preferences and the boxes are unticked for the IR remote and to use the Function buttons as proper F1-F12. When i tick the box the Funtion buttons work properly as standard windows ones. Any help would be greatly appreciated.
