Here are the results of my testing with the ASAP Utilities extra workbook appears then remains open at exit issue. My workstation is running 32bit Office 2013a under Windows 8.1 64bit. (Your Mileage May Vary)
• The blank-extra workbook only appears when Excel is started by double clicking an existing workbook file, NOT in a new workbook when Excel is started from the application shortcut.
• If the blank-extra workbook is closed first it also closes the other (real) workbook.
• The issue only occurs if ASAP Utilities is one of multiple Add-Ins that are enabled.
• The issue is NOT present if ASAP Utilities is the ONLY Add-In enabled.
• The issue is NOT present if ASAP Utilities is THE FIRST Add-In enabled of several.
• HERE IS THE CORRECTION THAT WORKED FOR ME:
1. Disable/uncheck ALL Add-Ins, and Close ALL workbook(s).
2. Open any workbook and Enable/check the ASAP Utilities ADD-In, then Close the workbook.
3. Open any workbook and enable/check the additional Add-In(s), then Close the workbook.
4. Open AN EXISTING-WORKBOOK FILE, and (hopefully) the blank-extra workbook will not open.
To explain the behavior in other words; ASAP Utilities seems to have a “me first” attitude. On my computer it just wants to be chosen first. Given the multitude of Add-In problems that are present in Office 2013, I am grateful that ASAP Utilities is still working at all – It is a great value and I encourage all users to make a contribution to the developer.
