Are you on a Mac Star Lizard? As Vitae is only sold through the Apple store there is no Trial version available.
Can you define “troubles” more specifically?
Dose ARV have any bugs?; Yes it dose. But then again all my other graphics apps do too!
Do any of ARV’s bugs impact my workflow sufficiently to prevent me working with the app; No, not in the least
. It’s mostly just quirky behaviour with some elements of the UI.
But without knowing your precise concerns it's a difficult one to answer...
ARV is currently on Sale for 50% off at the moment (I think it finishes in 3 or 4 days time) so from that point of view this would be the opportune moment to upgrade for less.
