Key Object Performance Issues
When aligning to a complex key object, the performance is terrible. When I click on a complex object (say, a group of complex paths or illustrations) to set it as the key object, it lags for several seconds after clicking before I can click an alignment tool. The length of the lag depends on how complex the key object is. This behavior never occurred in prior versions of illustrator. Very annoying.
