into pastepad clicked create pdf. wached rotating circle until I finally closed the page. push to kindle did in fact create a file as per save as dialog, but it had no file extension

I can’t reproduce this. Both regular Push to Kindle and Paste Pad work fine with this content for me. Could you try again perhaps? Does Paste Pad work for any other site for you? (If not, check to see if maybe you’ve disabled Javascript on the page.)
