[CONNECT U13] Closing Problem when no Auto Save

I think I found a bug. For development I turn of auto-save, as I did in Update 13. When closing the MicroStation, it ask to save the changes (Yes, No, Cancel) but the MicroStation already closed. When pressing Yes or No, this might not be an issue but pressing Cancel brings you in a weird state. The only window left is my Toolbox and it shows me the icons to dock. Doing this, just removes the window. Only solution is to kill the Task over the Taskmanager.

I did verify it with a clean installation on a VM. Also I do use use Version and not the newest U13 with the patches but this didn't got mentioned. The workaround would be to not press Cancel or turning on auto-save.
