Excel must be loaded in your system memory. If you hit Ctrl+Alt+Delete and
click 'Task Manager', do you any instances of Excel under the 'Processes' tab?

Maybe just before you exit the A.xls book you need to include something like

In the ThisWorkbook Object put a small snippet of code like this:
Private Sub Workbook_BeforeClose(Cancel As Boolean)
Call 'YourCloseMacroNameHere...see example in link above
End Sub
