Hiya! To answer your question, I don't think they're even working on a Vue 5 yet. They've had some problems with the Mac OS X version, and I bet they'll fix all that before starting a Vue 5. Vue is now up to 4.05-02, the ".05-02" being the latest patch, and I would assume they're working on a .06 patch to xsolve the last of the rather minor problems remaining. All the patches are free, of course, and currently it is 4.05-02 which is shipping on CD as a whole product, so you don't have to manually patch it. I would be surprised if Vue 5 gets released any time this year, actually. Of course, they have upgrade deals. I bought Vue when it was version 3.1, in the Summer of 2000, and in the Fall of 2001, upgraded to 4.0 for half the price of the full version. Good deal, really, because Vue 4 is FAR more advanced than Vue 3.1 was, and I imagine Vue 5 will continue in that tradition. I hope this helps you in your decision, and come back and see us! PS You can download a demo of Vue 4 Here. It allows you to render, with no watermark. :) Can't save though, and it expires after 30 days, but it has all the features of the full version.
