Enabling and disabling breakpoints
    
    
      Breakpoints can be enabled and disabled as needed.  When a breakpoint is enabled, thread execution suspends before that line of code is executed. 
      When a breakpoint is disabled, thread execution is not suspended by the
      presence of the breakpoint.

  -  Open the breakpoint's context menu and select Disable, 
    or deselect the breakpoint's checkbox.
-  The breakpoint image will change to a white circle and its checkbox will 
    be empty.
