### Macro draggableProof.pl conflicts with knowl and hint

Hello,

I am successfully using draggable proofs.  However, I have noticed that I cannot use HINTS or KNOWLS if I have the macro draggableProof.pl loaded.  I give a minimal example below.  The 3 macros below are ones that I have installed for the many draggable proofs exercises I have that work just fine -- when I remove the draggableProof.pl macro the hints and knowl work just fine.  I would like to use HINTS or KNOWLS with these draggable proofs problems however. Thanks for any thoughts the forum may have.

The JavaScript versions in the old version of ths macro conflict with other JavaScript in more recent versions of webwork. This has been fixed. I can email anyone a copy of the new macro which has a couple of other improvements. Send me a note at travis AT mc.edu.

Hi John. Thanks for sending me the newest draggableProof.pl file.  I did a Notepad++ compare of it and the older version I was using and only a few lines seem very different.

In any case, it is still not working.  The moment that I add the draggableProof.pl macro to the code, I lose the functionality of the Knowl and the HINT.  Bummer.
