I haven't used Access for many years, and have just re-started with Access 365. I designed my first form very simply to try things out - in Design View it was about 12 cms square and had just one control. However when opened the form completely filled the screen with no borders. The form header and control were in the right position relative to each other in the top left of the workspace. There were no scroll bars, so I couldn't see if the borders were somewhere beyond the screen. The width property was set to 12cms as I expected. I tried various other properties, but could make no difference.
How to I get it behave just like the old days? Any ideas will be gratefully received.
