With Puzzlemaker using the NuPACK folding engine, I encounter several issues.
(1) Copy sequence to clipboard fails (no pop-up success message shows and I confirmed that the issue is not just lack of the success message = the sequence is NOT copied to clipboard)
(2) Paste in a sequence from clipboard fails = no dialog box appears to enable the paste.
(3) A sequence seems to calculate differently even though I just turned into a puzzle (and solved it) http://www.eternagame.org/game/puzzle/6362581/ My window with puzzlemaker is NOT successfully solved - maybe . Confusing because I just built it there. Might be that it is not the same, but without copy and paste, it is hard to tell…
I was using Chrome (in case this is a browser-specific issue)
