If the Vue preview window was more flexible, and could be resized to the users satisfaction, then it would be a much more usefull tool.  I use a 24" LCD, and can get quite a bit bigger P-window without taking up too much work space, but it simply lacks that needed flexibility.  I'll bet that Vue 6 will have a  much more usable preview window?

I actually do like the "Select Render Area" option, with the ability to define a zoom; however, if the preview window helps out some artists, then it is doing its job for those folks.  I do think most would agree that a truely resizable preview window would be a big help.

BTW, comparing Carrara5 and Vue5 is inevitable when one owns both applications (I have a Vue render running on one of my PCs as I write this).  I also own C5Pro.
