impossible to reactivate a deactivated editor

[mokhet]

Take the full_example http://xinha.gogo.co.nz/xinha-nightly/examples/full_example.html

Ask to generate 2 editors.

click in first one, go to source mode

click in the second editor ( the icons of the first editor are then deactivated )

click back to the first editor, and now you are stuck in this mode and no buttons are reactivated.

This is probably related to #966.

This is is the same as #965 and fixed in rev [758]
