I will try to test this sometime, though I always start IDLE through the start menu.

BTW, ActivePython (2.6 and 2.7 at the moment) includes this patched idle.bat. The start menu shortcut launches it.

I don't think this is a feature request. This batch file should always run the version of the file for which the batch is installed. For it to be generic and end up using another installed version is incorrect. With that said...
Fixed in r86651, r86652, and r86653. Thanks for the patch.

Brian,
The following line:
 start %CURRDIR%..\..\pythonw.exe %CURRDIR%idle.pyw %1 %2 %3 %4 %5 %6 %7 %8 %9
should be changed to:
 start "%CURRDIR%..\..\pythonw.exe" "%CURRDIR%idle.pyw" %1 %2 %3 %4 %5 %6 %7 %8 %9
This is required if Python is installed into a directory with whitespace in its path.

True. I'll correct it.

Corrected in r86655, r86656, and r86657.

There is a bug with the patch. The first argument to the `start` command, if a quoted string, becomes the Window title, not the command to execute. Hence, idle.pyw is directly executed by Windows. Here's the correct command line:
start "IDLELAUNCH" "%CURRDIR%..\..\pythonw.exe" "%CURRDIR%idle.pyw" %1 %2 %3 %4 %5 %6 %7 %8 %9
Could you make this fix part of the upcoming 3.2?

We're only a few days away from 3.2 final so it's too late. Once it goes out I'll make the adjustment and it'll be in 3.2.1.
