I've written a spreadsheet that sometimes causes an error that shuts down Excel when the model is closed without saving. It doesn't always cause an error on no-save closes and never causes this error when saved while closing. Any ideas?
Well, I followed through each of the links you posted and they appear to be dead ends.
For what it's worth, the first time I open Excel and close the file without saving, it generally works. If I reopen the file again and close again without saving, it seems to error on the 2nd and later attempts. I think I've seen it on other very large (3+ MB) spreadsheets as well. This leads me to believe it has something to do with available memory and is not specific to this model.
