Please fix the breakpoint set/clear mishandling

[PC Pete]

When selecting text using the mouse, it is almost impossible NOT to accidentally set a breakpoint if the mouse ends up at the left margin.

My expectation from real pascal and most other GUI IDEs is that I must DOUBLE-CLICK the left margin to set/clear a breakpoint (or right-click and select add/clear, etc, depending on the IDE).

That would prevent the problem of accidental breakpoint setting AND would make the breakpoint display/handling much more robust and less error-prone.
Thanks!
