ActiveWorkbook.Close closing sheets, but not the window

Hi Guys,

I have a code that saves and closes (or should close) the workbook:

Sub SaveClose()

    ActiveWorkbook.Save
    ActiveWorkbook.Close False

End Sub

What it does instead is it closes all the sheets, but keeps the Excel blank window still open... Is it something wrong with the settings of my Excel or some global settings on my machine? Because when I searched around a bit for code to close workbooks, the above code appeared pretty much all the time (in different configurations sometimes).
