This has probably been asked loads of times but from the suggestions made in other threads or other forums I still can't get it to work. I've installed Apple K Pro and something from Randyrants.com. Both were rubbish, making unnessarily difficult ways around it. I have to use a PC at work but have a Mac as well which I find easier to use for certain tasks and now have them both connected to USB KVM Switch. Obviously I need Print Screen working so I can paste a screen shot into Outlook/Work/MSPaint. How difficult can it be?
