Hello,After running with SP1 for a bit, I sometimes experience strange behavior on push back. I was pushing back from KATL this evening with a distance of 131 feet straight back with a 0 degree turn specified in the CDU. The push back started, and did not stop. In addition, it did not push straight back. It wound up doing a 270 degree turn to the left. I've experienced this behavior before when I specified a direction turn. This is the first time I experienced this problem with a command to push straight back. I do not recall experiencing this problem before SP1.Any advice would be greatly appreciated.Thanks!Mike Murphy

I had that once before (pre SP1),that it pushed back and never stopped, but I never experienced this behavior since then.
