THIS IS still a problem. I reported it over a year ago (with a video as well) and confirmed it with Tech support at the time, and they said it would be fixed in a future version. Here we are with 4.1.1 and STILL THIS CAMERA IS MADDENING. It is so frustrating to circle a model with your camera up close (up close is key), and the camera WILL NOT STAY ON THE CENTER YOU PLACED IT ON! It drifts all over the place usually back to some imaginary center of the build space. Sorry... it's just frustrating. I love S3D and think it might be the best slicer on the market. I'm completely puzzled that you would carry such a glaring fault for so long, esp when it's been reported and confirmed.
Not using anything special here... standard PC WIN7-64, normal 101 keyboard and USB mouse.
