Blank workbook on Excel startup stays open

[cr731]

Normally, when I used to open Excel, a blank workbook is opened along with Excel, and if I do nothing to this blank workbook and then open an existing file, that blank startup workbook is discarded automatically upon the new file opening.

I recently updated to Version 1708 (Build 8431.2094) in Office 365 Click-To-Run Monthly Channel, and now, that blank workbook on startup remains open even if I do nothing to it before opening another file. This means I need to manually close that workbook every time Excel opens.

I haven't made any other changes aside from the update (no changes to XLSTART or anything else).

If anyone else has this version or later, can you let me know how the blank workbook on startup is handled?

Thanks

Not sure if this in 365, but have a look at this
