That's it, Redneckdude! I used to have IconPackager for Windows XP and had fun with it then, but had forgotten it was a separate product. Thanks for reminding me!
Also, on the "flash" question mentioned above, does that refer to the problem with the folder staying at the point at which we've scrolled down to find a file? I might have to uninstall Win10 because of that -- the folder leaps back to the top of the window before I can select the file I want to edit. (It just started that tonight after earlier icon problem post. I'm told it might have to do with wallpaper shuffle changes, which would really be a strange bug! -- Any ideas?
Thank you!
