- Using the mouse, position the cursor on a line of code (e.g. line 38)
- Without changing the mouse position, click in the breakpoint margin on a different line of code (e.g. line 51).
- Notice that the breakpoint appears on line 38, instead of the expected line 51.
- Clicking again in line 51's margin removes the breakpoint on line 38.
