Hi Denis ...
As a MOI user I would like to point out that a registered user gets to use the next betas throughout their development period - which could take a year.
As a Ver 1 user I was using Ver 2 throughout its wonderful development period ... unlike most betas MOI never had a serious glitch ... it just got better and better.
So I suggest you buy MOI ver 2 now and in a week or so you will be able to use ver 3 without having to wait for the final version.
cheers
eric
