I have an addin for a toolbar to toggle calculation on and off.

Everything works fine.
I am tracking the current status by checking everytime the
TrackEvent_SheetChange fires.
I do have people who have written macros that turn off calculation and
never set it back, or they change it manually.

I want this toggle button to always reflect the current state of auto
or manual, so if something has changed I want the button to
auto-update itself.
Everything works, I only wonder if there is another approach to check
the status, than firing on the TrackEvent_SheetChange.

Thanks,
Scott Denton
