Half Baked Software, the makers of Hot Potatoes and Quandary, have released these programs as freeware. This means that anyone can go and download the latest version of these programs for free from the Hot Potatoes website.
So, if you use an older limited version of Hot Potatoes 6 or Quandary 2, we advise you to remove it from your PC and download and install the unlimited freeware version. These latest versions (as of February 2010) are Hot Potatoes 6.3 and Quandary 2.4. If you still have a (licensed) version of Hot Potatoes 5 or Quandary 1, you are advised to keep those and install the newer versions on the side.
