Setting breakpoints in a mixed mode file? (New post Google HasCorrupted Link)

When I set a break point in a file that has both managed C++ and
unmanaged C++ the debugger never sees the breakpoints in the managed
code. What can be done to get the debugger to "see" the breakpoints
in
the managed code?

I just tried enabling the mixed mode debugging option, and then marked
the breakpoint. Visual Studio used a hollow red dot indicating that
the breakpoint would not be triggered. I do know that the line-of-code
is reached because it prints its line-of-text to its output file, yet
the breakpoint is still not reached in debug mode.
