Why won't foo_ui_classic compile? 2003-06-23 04:50:04 After doing some searching around, I found a fairly easy way to implement support for the media keys on my Microsoft Multimedia Natural keyboard... The only problem is that foo_ui_classic won't compile. I have the dependencies set up for SDK and PFC, but it keeps giving me a "cannot instantiate abstract class" error. Is this happening for a specific reason, or am I just dumb (or both)?
