Hi Bob

Just to let you know I worked out what the problem was. There is a yellow line in The Sky X called Telescope Limit. For some reason this line was in a position that was not at the meridian but over by 0.33 Ha, on the east side of the meridian. So when the mount moved the telescope to that position it would produce this error. I had forgotten that some time ago I had this problem and had been helped on the Bisque forum as I had noticed it but didn't know how to move it . So now I have just dragged it by a little square that is attached to part of the yellow line, to the meridian, and now I think things are working okay again, well so far.
