SGP Performance..latest version-Plate Solving

Have to say that last weekend SGP performed beautifully targeting and plate solving (pinpoint) NGC6823 at a focal length of 1050mm.
What I always have an issue (partly my fault) is when I use the Frame and Focus module and I try to stop a shooting sequence…sometimes it jams (or something) and pressing Start again doesnt work.
Anyone had this problem before?
