Anyone here use LDD? I'm curious to know what people think of it...I tried downloading a copy onto my laptop, but sadly it doesn't seem to function properly (The screen keeps flashing and won't let me click anything). The laptop is an MSI X320 running Windows Vista. During the installation, it popped up a message about needing a new OpenGL driver, but I haven't been able to locate an appropriate one for my particular laptop (may have something to do with the fact that I have no idea what OpenGL is... or where to look for one). I'm also looking into getting LDraw, in case that doesn't work out. Has anyone here used both? If so, which would you recommend?
