When searching a marked source term in resources, this term will also be looked up in the MT engines (with sometimes different results than in the MT of the whole sentence).
But when the MT engines are docked to the tabbed pane (instead of their "standard" position, this lookup does not take place.
In the very most cases I do not need this lookup, but this different behavior is a bit irritating (although it is not critical). I did not test this out for any other tab position.
Is any of these 2 behaviors a bug or a feature?
