Re: Python functionality on Windows
If it is only about pythonw, the fix is actually very simple on Windows. I
submitted a patch into the Winbuilder bug-tracker,
https://github.com/nickoe/KiCad-Winbuilder/issues/28. Perhaps, the fix can be
equally simple on other platforms, I have no idea how the build is performed
there.
Martin.
