I have a workbook which I use with 3 add-ins that I wrote. Add-ins trigger
beforeclose and beforesave event on different occasions. Everything seems to
work fine in my personal notebook or in a test-desktop, but when I install
add-ins to other computers I begin to get crashes. It usually happens when I
close Excel. DrWatson Log has something like this:
