The cursor issue has been addressed and the pack is updated. To make sure everything is working fine (and there are no leftover files from the pack) I suggest to re-install Discovery and afterwards install the updated pack (version 1.2.1).
More details are in the Download section on the original post.
On a related note, sorry it took me a while to fix this. I'm only checking this thread every once in a while. If you find a problem with the pack, send me a personal message on the forums. That way I get an email notification and can respond faster.
