draw_f0_curves_from_files.praat bug?

[speechchemistry]

Hi, really appreciating using your scripts. The script draw_f0_curves_from_files.praat seems to crash on my system with the error 'wrong field in command window "run script: draw pitch curves from all sounds files in directory'. That's the initial form it's referring to, and it happens as soon as I press apply or OK on that form with the default values or my own values. I'm using Praat 6.0.37 on Windows 10. As you allude to in the SpeCT webpage, is possible that the Praat commands have been updated. Unfortunately I don't know how to script in Praat so I can't fix it myself.
