The latest version of IDLE was *supposed* to fix this by restarting
the IDLE session when you run the script.
Unfortunately they didn't get it working on the windows version
because it uses the same socket when you run multiple
versions......... The result is that IDLE is virtually unuseable for
serious work on windows... :-(

There *is* a way round it...... If you edit your file association for
.py and .pyw files (from an explorer window menu select tools and
folder options - then choose file types). Remove the -n from the
command line that IDLE is launched with.. this allows IDLE to be
launched with a subprocess... *HOWEVER* if you do this you can only
open one version of IDLE at a time the second and third
modules/scripts that you edit must be opened using the 'open' or 'open
module' option..... If a second shell window opens it will

I have two file associations - one 'Edit with IDLE Subprocess' and one
'Edit with IDLE No Subprocess'... the two co-exist quite happily even
when run simultaneously...........

For files edited on IDLE *with* a subprocess - it will restart the
session whenever you run the script...... which re-imports all the
modules and therefore includes your changes..... bit of a bodge
