I am running Python 3.1.2 with IDLE 3.1.2 on Windows 7. When I try to use the Stack Viewer, blue text and a new window briefly appear before all open IDLE windows exit (I don't have time to read the text or new window). This is the first time I have used Stack Viewer.
Is this normal behavior? How can I get the Stack Viewer to stay open?
Thanks for your help,
Alex
I don't have Windows so I can't help you with hands-on experience, but I would do the following:

see what is the exact command that runs when you click on the menu item for Idle (I think you can right-click and see its properties, or at least you could on earlier versions of Windows)
open a command prompt, and run the command that opens Idle
open the stack viewer and then note the traceback that (should!) appear in the command prompt window
report said traceback here :)

BTW, in my installation (neither Windows nor Python 3.x), an attempt to open the stack viewer without a traceback produces the following message box:

Title: No stack trace
Message: There is no stack trace yet.
(sys.last_traceback is not defined)
(Python, IDLE, Windows) Pressing Stack Viewer exits all IDLE windows
