You can examine breakpoint locations any time the project is open. Select Debug -> Breakpoints to get the Breakpoints dialog box, which contains a list of breakpoints. Selecting one of the breakpoints in the list enables the Delete push button if the project is running in debug mode. It also enables the Show source push button. Pressing this push button opens a view window for the source file containing the breakpoint, and puts the line with the breakpoint approximately in the centre of the window.
