Breakpoints in Microsoft Access 2.0 are removed from a module when the code window is closed. Therefore it's a little tricky to set breakpoints in code fired by the form's OnOpen event. Here's how you do it: First open the form's code window by selecting the form in the database container and pressing the View Code button on the toolbar. This will open the form in design view and open the form's code window. Find the statement where you want to set the breakpoint, and set it with the Toggle Breakpoint command on the right-click menu. Finally, move to the form (without closing the module) and press the Browse button on the toolbar. This will start the full suite of form events including the OnOpen event.
