I am using Excel 2004 for the Mac (v11.1) and running OSX.

My keypad will only function in cursor movement mode and will not lock into number mode. This only occurs in Excel. If I use any other application, the numlock key works and the keypad can be used to enter numbers.

I'm pretty sure that this just started happening in the past few weeks or surely I would have noticed since I got this computer in July '04.

Any ideas out there? It is quite possible that a small child or cat could have hit some series of key strokes to create this problem.
