This isn't a known problem. I have the analysis toolpak addin selected and
workbook_Open runs fine for me. Perhaps you have something in workbook open
that conflicts with something in the analysis toolpak.

Is this a consistent repeatable behavior - that occurs even after you
reboot? Does it happen with multiple workbooks?

I have a Workbook_Open macro in the ThisWorkbook module that is not
running. If I un-select the Analysis Tool Pack add-in, it runs just fine.
How do I get both of these things to work together?
