Fix regression of control disabling, bug #423
Fix regression of control disabling, bug #423

This fixes incorrect reenabling of the manual controls while a program is
running.  This was an unintended consequence from 55d93a8f

Most of 55d93a8f had already been reverted to fix other breakage; see b6015c28
and 1775f4f9
