Thanks for your attention Joe.
Really I don't know what happening. About two things you say me: 'Compilation Debug' in Web.confg and 'Debug' in VS are Ok. And, for other side I see the IIS and flags for debug are ON (in tab Virtual Dir. - Configuration - Debug). In Addition, I put a lot of breakpoint, but the application still go a head without stop.
Please, any question I will be ready to answer, because I need to solve this!
Thanks in advance...
