Thanks to the VFPT in order not to have rendered all the my job completely useless in order to improve VFP.
I think can be useful to bring back a list of the problems that me seem resolved.

Thread #900095 confirmed
Thread #824792 not confirmed


Of course those remained opened, are still numerous,
but me it seems to have noticed that if is reproduced well,
the Team (with the human resources that it has to disposition) tries to resolve them.

Of course, it remains the fact that for sure errors can be necessary much time in order to write the minimal code that reproduces it well.

Ill-fatedly the greater part is problems legacies to modalities
of miscalculation or not standard,
and for these road is not difficult to find one alternative.

Where it is often difficult or impossible to find an alternative is when the errors are taken place in the events of the objects.
Here me seems that we are still far from a satisfactory level.
