I have some code that is triggered when the user selects a sheet within a
workbook. It redraws a menu, which changes from sheet to sheet.

The problem is that this takes some time to run, and when you're running
functions that cycle through the sheets (and we have lots of these) the delay
while the menu redraws actually becomes a significant time waster.

So what I'd like to do is have this code fire not when the workbood simply
changes tabs, but when the USER does this. Any ideas?
