Having continued problems with script failure when attempting the beginning of OSC. Was advised last time I had a problem to change my file names which I did and it worked. Now introduced some new files but cannot get past go. In main drive with last successful process I had a file called Manapouri 1, if you clicked on that , a file Manapouri 1 opened and if you clicked that you saw all the light and calibration frames. This still works !! Now I have a file in main drive called Bastro Serpentine Dam, click on it and you get a file Bastro Serpentine Dam, if you click again you get the light and calibration frames showing. Can somebody tell me how this last set of files processing is any different than the first lot which I can process and it works ? Lost. Russell
