Intex - There is not a new option, button, or anything to have it select a random poll - You just put RAND in the "Polls Forum ID" field. It should have a note about that in the description for that field, but it's possible I forgot to add that if you were upgrading. As far as the latest threads part, check to see if you have modified your index_threadbit template. If so, try reverting it to the original and it should have the mouse over effect then.
One other thing... Have you used the poll on your homepage since you've installed the hack? There was a new function added to vBulletin in 2.2.6 that this script uses, so everyone that has tried to use the poll for an earlier version so far has had problems. If you do have a problem, see
this post for the fix.
frankenberrie - See the first part of my reply to Intex.
Littlebit - Did you by chance upgrade to 3.2.1 before Intex found those 2 small bugs above? It's possible that one of those could be the cause if you did. If so, try downloading the script again (remember you may have to clear your temporary internet files first) and upload the file again... Or you could just try applying the patch I posted in post #1270 (that's the one that could affect the news posts) and the fix posted in #1267. If that doesn't work though let me know and I'll look into it.
