#1 do you have a Wacom tablet? I have a lot of issues with the drivers. In all 3D packages. So for Vue, Poser, Cinema etc i use the normal mouse, for the rest the graphic tablet. It could be that V5 interpretates your mouse movement as a drag and drop issue. You can give an object a material by simply dropping the material icon onto the model in the scene. #2 procedural terrains are a little tricky. I will test that the next days. #3 I always answer with "no" because of the reset it does to the preferences. A simple trick. Backup the folder "environment". In there there are files with the extention .env. They contain the informations about your settings. Restore them and all your settings are back. I will tell you early next week which one does what. In 4 it was easier because there it was all one file, Vue.env. In V5 it has changed to several files. For the several issues.
