Hi all, I installed the Demo to try and see if BTB works on my rig with Win7 64bit before eventually purchase a licence. As of now I have noticed the following "Problems" and was wondering if someone could help me out: 1. In any view, I can not select or "Click and Drag" multiple terrain anchors. If I draw a vague shape around the anchors to select them, either nothing happens or only some are selected. This makes it impossible for me to edit Terrain properly as it would take ages to do it anchor-by-anchor. 2. I can change the material of the terrain but I am unable to do it with the road or the walls, something like "there must be at least one surface"-message pops up. Also, I don't see any other option for road or wall material. Is this due to the Demo? 3. In 3-D View the mouse commands are extremely slow, it takes forever to zoom in or out or move along the track with the middle-button. It's much faster in top- or side-view. Program starts and runs fine. (did not try to run it in XP-compatibility mode though). Any kind of help is appreciated! Am I doing something wrong? Are there commands that I did not see? Thank you very much!
