I haven't tested yet (just reviewed the diff), but a couple of
thoughts come to mind:

- Can we disable the controls on the form, rather than the tabs so the
user can still browse the object details after modfying the SQL? (Or
does disabling the tab effectively do that?). The downside of that is
that we'd need to keep track of which controls were already disabled
when we disable them all, so if re-enabling them we end up in the
original state. I realise this is not what I suggested previously.

- Before returning to GUI mode, we should warn the user (if he has
modified the SQL) that his changes will be lost. Of he accepts the
change, the SQL should be regenerated immediately.

So, before I test this on my lapdog, I'm sure we all want to know -
did anything actually explode?
