I was!  Sadly I don't have any good way of recording my screen, but the gist of level 6 is:

• Push the lower crate right; pull it down; pull it away from the wall, go around to the other side of it, and push it south of the middle camera. (Then go ahead and push it north, until it's two spaces south of the camera.)
• Go south of the crate and around the top of the bricks, and put out the leftmost camera from above.
• Go back around the crate and get the northern crate; pull it south three times, pull it east once, then go back around it and push it east until it's on the space below the middle camera.
• Now push the southern crate east, until it's just short of the last camera.  Pull it north once, go to its west and push it east once so it's blocking the camera, then go to its south and push it north.  Then you can get to the exit.

(There's also a small bug, where if you push the crate so that it's east of the middle camera, it "blocks" that camera, making the square between it and the exit passable even though there's another camera looking at it.  But I didn't exploit that. :-) )
