3d intensity issue

So, I went into MA3 today and when I put a group at full nothing happened in the 3d window. At first I thought my main or world master was down but they are both at full. The fixtures don't show intensity in the selection grid either, but they do in the fixture sheet. The fixtures are also not moving when I provide pan/tilt data. It's like they're frozen. Any help would be appreciated!! Thanks

Looks like it's working now after I re-started MA3. Super strange...
