Thanks for the explanation Keith, guess I must have been lucky with the flames that I created! I fully agree that it would be a huge shame, not to mention a massive retrograde step if Apo were to lose UF compatability. Tina, it is not neccessary to overwrite your current version of Apo with 2.03 - just install to a different directory, and keep the two separate, that way you can continue to use your current version whilst experimenting with the new.
