Hi Sean,

Sorry for the long delay before answering...

Yes, there is a way. You need to edit your registry and remove the -n
flag which is used when running IDLE via the "Edit with IDLE"
context-menu option.

If you do this, however, you will only be able to open one instance of
IDLE at a time in this way; trying to open another one in the same
manner will cause a 10 second delay after which you will receive an
annoying error message.

There is a way to get this working smoothly with as many instances of
IDLE as you like, but that requires patching your version of IDLE. I'd
be glad to explain how if you're that motivated :)
