Hi Michael!

Yeah, quickly searching went right to tkdnd. We're still Python2, so no problem there.

I'm starting to think that copy and paste into a window may be the only option, but I'm not sure what Xming/XQuartz will do with the file.

Oh, well, I Command-C'ed a text file on my Mac to a Toplevel in the program with Ctrl-V and the file name was typed in the Text(). That's cute. :) "Paste" didn't even show up in the XQuartz Edit menu after the Command-C. This may just not be possible.

I guess I could give everyone a little utility that produces a uuencode'd file from their .gif, or whatever, on their Desktop, and then they copy and paste the contents of that into a program's Toplevel/Text() after opening it with their favorite text editor. Then select a menu item to suck in whatever it was they pasted.

Are users that smart? Dang. ;)

Thanks!
