2.2 vs. 1.8: Save button stays readonly if a field is changed
When the content of a field (char, text) is changed by the user, the save button
in the toolbar stays in-sensitive, as long as the focus leaves the field.
In 1.8 the save button was becoming sensitive, while the field contents changed.
For mouse users it is one click more, to leave the field, for getting the save
button sensitive and save the record.
Anyway it is possible to use ctrl-s to save the record, even when the save
button is insensitive.
