No doubt auto backup is a feature of many programs, both high and low end. And although it does have its uses, it would hardly seem worth the effort. That's like one of those icing-on-the-cake things, something you add after all the really important stuff is there.
All I'm saying is I would consider an auto backup to be a fairly low priority feature, as long as my synapses are functioning well enough that I can remember to deal with saving and/or backing up on my own.
How about instead of fixing nonexistent problems or adding inconsequential features they do something about some of the seriously annoying things.
Like, why does it take Poser 5 minutes to load all the textures in a big scene before a render? How is it other programs have the textures loaded, noted, categorized, filed in triplicate and ready to go, but Poser needs some extra prep work? What's it doing anyway? Approving them individually by committee or something?
And what's it doing after the render where it takes 20 seconds to think about its next step? You know, after you get out of render mode and want to start doing stuff again. Meanwhile, Poser is...what? Trying to remember what it was being asked to do? Or are both of those things symptoms of the memory problem that's been with Poser forever?
