When i have a zz exported workbook open, minor action in other excel sheets crash the app. This is the error. It is occurring on several workstations in our office.

Hey John, thanks for reporting. Could you send the Excel File to support@zztakeoff.com or our website support so we can take a look at it on our end? Doing a quick search online, this could be an issue with too much styling embedded in the Excel sheet, or your font cache in Windows could be corrupted.
For me this occured with any ZZtakeoff quantity takeoff export if I have one or more other excel files open at the same time (something that is almost always true). Won't let me change fonts, bold, etc. within the other files and can crash excel.
