Bruce: Thanks for correcting my earlier posting error! The problem with loading IDLE from the shell context menu is that the default binding runs IDLE with the "no subprocess" command line option (you can see this in the output window if you look, and you can correct it by changing the command line for the "Edit" action in explorer by hand). My guess is that this is because of some real or perceived problem with running multiple instances of IDLE in the usual subprocess mode. I think it would be a good idea to remove the "no subprocess" option from the shell binding, and fix any problem with the coexistence of multiple subprocess-based IDLE instances.
Douglas: Your use of IDLE, like ours, required some similar changes. Perhaps Dave > can list out, point by point, the changes the patch makes, and we can > discuss those? The patch is really very simple: when IDLE wants to terminate the subprocess, it uses the most direct and powerful command available from the operating system to do it, instead of asking the subprocess to terminate itself in a relatively unreliable way. This is the most straightforward, easy, efficient and elegant way to do the job. The only reason it's more than a couple of lines of code is because Python provides slightly different interfaces to do this on UNIX and Windows (reflecting the slightly different operating system APIs).

It's one of the major advantages of the subprocess model. Please let us know how my patch works for you! Dave
