#27 Breakpoint not working

[Anonymous]

Using:
ruby 1.8.7 (2008-08-11 patchlevel 72) [i386-mswin32]
RDE 1.1.1.1 by Sakazuki
On XP 2002 SP2

Breakpoints highlight on the screen but don't appear to work (i.e. no stopping at the point set), the code is definately running, and the break point is being 'passed' during the run (good old fashioned 'printf')

It work but not as I expected.

Open option and fill up command as follow.

Options > Debug Commands
Debug Mode: -r debug
Normal Mode:
Step In: step
Step Over: next
continue: cont
Quit: quit

Step in and Step over command open the Library files!
Somebody know a way to avoid that?
