I've found that this crash seems to happen when dragging to the Taskbar (and more accurately it always happens the second time I try to drag to the task bar). I believe we are going to look into a fix but I am curious if you are also dragging to the task bar when the crash happens. If are you, what if you switch to Photoshop by using alt-tab on your keyboard rather than dragging to the task bar? Does that avoid the crash.
