Logic Pro 7: Instruments open up in Controls view after double-clicking

When double-clicking an instrument in the Input slot, the plug-in opens in the Controls view instead of the Editor view.

This can happen after dragging a software instrument loop (e.g. "70s ballad drums") from the Loop Browser onto an Audio Instrument track.

When this happens, switch to Editor view manually via the Editor menu at the top of the plug-in window.
