I just started and I'm watching a tutorial video and the very first thing the tutorial does is "grab" the map right after opening a new project. See this video (the exact time is 1 min 3 seconds): notice he grabs the map and moves it around. On my program, its entirely stuck. I click left button, click right button, click both buttons, the map wont budge. So I couldn't even escape the tutorial :( I'm using Terragen 4 pro.
He's using MMB to manipulate the camera view. Sounds like he's saying "R" button, but that'd be the RTP.

thanks! I got it working :)
