Show One WorkBook while Not showing ThisWorkBook.

Not sure if this is possible.

I am running an XLSM that (via forms) creates a Workbook, that the user might want to work on before saving it as XLSX.

While the WorkBook/WorkSheet is being built, I have set up Application.Visible = False; this is to Not allow "ThisWorkBook" to show.

But this cause the other WorkBook Not to show too.

Is the a way to have one workbook shown while ThisWorkBook is kept hidden?

Thanks
