The number keypad on the right side of my mac keyboard has mysteriously stopped working the other day when using the windows side of my imac. The number pad does work with the mac side so I know it is not a physical problem with the keyboard. The homerow numbers work fine on the windows side.. How do I enable a "Numbers Lock" with a mac keyboard in windows xp? Has anyone else had a similar problem? Thank you very much in advance to those that can help!!
