Crusty Logic is best viewed with Mozilla Firefox. Apple’s Safari and Google’s Chrome work well too. Have not yet fully tested with Opera. It does not work as well in Internet Explorer though I hope this will be fixed in a future release of Explorer.
If you haven’t already, I urge you to try Firefox. There’s a reason it is the browser of choice within the computer industry, has recently become the number one browser in Europe, and is continuing to grow its usage throughout the world.
