Good one.  It's caused by the change I made at 

EditorWindow.py Rev 1.37

to fix the beep at the prompt and allow a tab to be backspaced.

I usually start with the shell window so I didn't see it.  It's caused by
sys.ps1 not being set until the shell starts.

Workaround, select start with the shell.

I'll fix it.
