Excel 2003 or 2007. Looking to be able to force spell checking whenever any
cell content is is changed. I've been successful on a single workbooks by
adding Spell Check execution on Worksheet_Change.

I'm hoping to take this one step further - make it an 'Add-In' so the check
will run for any workbook. It looks like the Worksheet_Change event only
triggers for the host workbook so an 'Add-in' will not do the job.

Any suggestions to force spell checking on a change for any
workbook/worksheet I modifiy?

TIA,
- Pat
