About once a day, when I click on an object with the direct selection tool, the bounding box will be way larger than it should, implying another object on another artboard is included in the selection.

This happens when the object I am selecting is NOT grouped with anything else. Moreover, is seems buggy because the mystery object doesnt have its "edges" visible the way it would if it were legitimately selected.

I can deselect all, but then anything I click on, the selection's bounding box is expanded to include the mystery object. The only way I have found to deal with it is to drag a corner of the bounding box, then undo, and then click off again. Then Voila! I am able to select my object (or any other) without the mystery selection happening.

I use clipping masks a lot, as well as many artboards, and have wondered if it's related to this, as the mystery objects are sometimes masked images, and often on another artboard. However, the mystery objects are not always masked.

Anyone else having this weird problem??

I had it with CS5, and hoped it would go away with CS6, but it has not.
