- Open BP lib, select a BP or book. (Don't close the lib after!)
- No select some item from the quickbar.
- Now you're still holding the BP/book from the lib, and the second item you selected.

This doesn't happen if you close the BP lib before selecting the second item. It also sorts itself out as soon as the BP lib window is closed.

Thanks for the report, since it doesn't break anything and it sorts itself out almost instantly, I would move it to minor issues.
