Michael L Hale,
Thanks for this bit of code. It is exactly what I need to automate an action that combines two open files without the prompt. Only thing I would like to ask your help now is how would I disable the auto-align feature using this script? I took your code (from July 14, 2010) and saved it as a .jsx but when using the script the auto-align layers feature is called up automatically and is slows the whole action down substantially. I tried digging around the the original load files into stack.jsx for the answer but could not figure it out.
Any suggestions to add to your bit of code to disable that feature. I'm running PS CC. Thanks so much!
