Default Bug in Fins on NC?

I have been using Rocksim 9 to play with a rkt file copied from the Semroc Snake Jumper to Groony a Fireball XL5. I have added four small triangular fins on the forward part of the BT. Everything was fine. I then decided to move the fins from the BT out on to the NC by using the definition of from the nose tip for position. This enabled using the automatic curvature calculation for the base of the fin, which worked perfectly also. I then attempted to make a change to the fin dimension by clicking on the fin plot point (custom fin defined) to move the tip of the fin further from the NC increasing the X dimension. The program basically locks up. The cursor locks into a selection tool (finger) and the disk drive spins up. Not sure if this would clear if I waited, but CTRL ALT DEL drops to the OS, which if you cancel the operation then Rocksim is still open and the last moved location of the plot point has been painted.

I have attached the .rkt file so this could be duplicated. If you select the forward fin set (third down in the fins on the hierarchy) and attempt to change the tip position to increase the span or chord it should lock up. Any ideas?
