Pempro Polar Align Wizard and SGP Issue

Hi Ray
I ran PEMPro quite a few times. In most cases (after a while) I got the warning message 'Camera busy,' the only option is to click ok and all the PEMPro trace information disappears off the screen, although if I remember correctly the elapsed time was still counting. On the other occasions the screen goes dim and the message 'SGpro has stopped working and Windows will close the program' (or words to that effect).
Regards. Adrian
