>When I open a code window for a class method and double click in the left margin next to a line, VFP will correctly put a marker in the margin and set up a breakpoint for that line of code. However, when I run my app with the debugger open, the debugger does not stop at the breakpoint at all. I know that the method code is being hit because if I type SET STEP ON just before the breakpoint line, the debugger stops appropriately.

When you set a breakpoint like this, the breakpoint has the form:

baseclass::baseclass.method,line

If this class is subclassed, and the subclass or the object also has code in the method--of course you're calling DODEFAULT()--the breakpoint won't work as is. You have to change it to use the form:

Object.Method,Line

The bp as is will work except under these conditions, or so far as I've been able to discern.
