my num pad(the block of number keys on the right side) on my reguar, not pro apple keyboard just turned off. the numlock key doesn't do anything, and they used to work as of a week or so ago. I did reciently install and uninstall a few key binding apps (ikey and hotapp) but it was for a totally unrelated purpose, and i didn't try to bind anyhting to thoes keys. Also when i hold shift, the keys do function properly. any ideas what went wrong?
