A family of Microsoft relational database management systems designed for ease of use.
I found the same problem with a form I had designed. I found that all of the objects were located in the "Form Header" with nothing in the "Detail" section. As an experiment, I moved everything to the "Detail" section and what do you know; the vertical scroll bar appeared!
NOTE: I did need to reset the events to the VB code to the controls with Events, seems they are reset to nothing when moving them from "Form Header to "Detail". It worked out OK just select the event procedure lost, click the "..." button and it reattached to the VB code.
Lots of Luck
