OK, here's what you need to do.
Click on the round Office Button in the top left hand corner of your screen. Along the Bottom margin of the dialogue window that will open you will see a button labelled Access Options, click this button. A new dialogue box will open, click on Current Database from the list in the left margin. About a third the way down you will see a heading Document Window Options select Overlapping Windows from the two options, and click the OK button. Another Dialogue window will advise you that you will need to close save and close the DB, before the changes you have made will take effect.
