Hello all,

We have some large workbooks that can take quite a bit of time to calculate when they are opened, if they don't lock up Excel.
The problem is if we have other unsaved workbooks open when we open one of these AND it crashes Excel, we lose the changes made
to these other workbooks.

I was wondering if the Workbook_Open event occurs before the sheet starts to calculate? If I put code in this event to turn off
Automatic Calculation, will it keep Excel from calculating?
