I finally took the plunge and purchased the minimum crossgrade. Installation was quick and easy. Already I see huge improvements on L4. L5 program runs faster and smoother (I have an old white macbook running OSX 10.6.8 with 4G memory and about 48 G left on my hard drive). I just started playing with the biblical places and people tool and am blown away by how much this is improved over L4 - so much info available in an incredibly intuitive and attractive format.
Great job Logos. It was a hickup with the launch. If the package comparison chart had been as clear at the beginning as it is now, and if there had been information available prominently about minimum crossover when L5 was first launched, you may have saved yourself a lot of headache. But it's clear that you listened to customers and, so far at least, I am very impressed with the new version. Well worth the upgrade cost.
Thanks!
