Built-in fields mandatory

[Reindero]

I would like to have some build in fields to be mandatory when a certain status is rewached. E.g. the field fixed in version must be mandatory when the status goes to resolved. This can be done with custom fields, but not with standard fields....why is this? And how can I cahnge it?

Regards,
Reinder
