Hi all,
IDLE refuses to launch, and I believe it is because I attempted to define a custom key-binding that it doesn't like.
I was recently defining a custom keybinding in IDLE 1.1 under Python 2.4 on WinMe. (I was using the simpler of the two binding definition interfaces.) When done, I hit the buttons for 'OK' (or however it is labelled -- I cannot currently check), but the definition dialog remained open. After several tries, I hit cancel, and IDLE terminated. (Whereas I expected the definition interface to close and return my to my unsaved :-( session.)
Afterwards, IDLE refused to launch. I tried various things, including reboot and eventually tried to run idle.pyw (the target of various shortcuts, etc.) by clicking on it. Nothing. Ran idle.py instead. The DOS-console this brings up displays:
Traceback (most recent call last):

I read through the various bits of code pointed at in the traceback. But, I'm a Python hobbyist, and have barely gone further than 'Hello World' with Tkinter. So, I don't know what to do with the information in the traceback.
I've looked at a number of 'IDLE won't start threads' that google knows about, but didn't see anything I recognized as useful. (Admittedly, I didn't read every single google hit :-)
Further, the last line of the traceback makes me think mine might be a somewhat unusual case. The keybinding I was defining when the excrement hit the air-conditioning was to make Shift + TAB perform a dedent on a region.
I did a search for files names *.p* (STAR.pSTAR for those whose mail-readers will take the wildcards as mark-up) modified today, hoping to track down the line defining the keybinding and remove it, but came up empty.
So, I'm at the end of what I can usefully do by way of diagnosis and repair.
Suggestions? (Anything gratefully received, but I favour being taught to fish over being fed merely for today.)
Thanks and best,
Brian vdB
