mouse
 * activate Gorms menu -> Edit -> Set Name...
 * enter a new name, and click the set name button

Backtrace is as follows:

2013-05-26 10:49:08.130 Gorm[27147] the OLD name ImageWindow and its class
name: LMWindow, and cc: {ImageView = LMFlipView; ImageWindow = LMWindow; }

This is always reproducible.
