I was trying to run the LayersToPNG.jsx script to export a PSD and before the options dialog box even appeared I received the follow error message: "Error 22: Window does not have a constructor. Line 233 -> var dialog = new Window("dialog", "Spine" LayersToPNG");
*see attachment for screenshot of the error message

I recently upgraded my system from MacOS Lion to MacOS El Capitan. I never had this error occur while using Lion.
Also, it appears that the file itself isn't the problem since I sent my file to someone else and they were able to run the script for me.
(Also, I'm using PS CS6)

Does anyone have any ideas of ways to fix/get around this error?

Thanks a bunch. Resetting my Photoshop preferences seemed to do the trick. Don't know if I'll have to reset them each day I need to run the script, but it certainly works.

My apologies for not replying sooner (I haven't needed to use Spine for a couple weeks). I ran the export script today and it didn't require me to reset my preferences again. So it may have been a one-time thing that needed to be done after upgrading my OS.
