Trouble accessing legacy instruments in the Library in Logic 10

If you just installed Logic 10 It's a simple bug to work around.

First do it the hard way...

In the inspector (left column) click on the instrument for your selected Instrument track.

In the popup hover the mouse over Legacy and navigate to any instrument.

You will then see the Library restore the links to the Legacy Instruments which should be a "permanent" fix from now on.
