Thanks for the response! I haven't tried anything else yet (only several different versions of SGP). My next diagnostic step is to try a new cable and a different computer to rule out the cabling and/or the USB bus on the machine.
Nothing changed (which is the weird part). The scope was setup one night, covered during the day and restarted again the next night without any config change...it worked perfectly (as usual) the first night, then started giving me trouble the second night.
I'm going to give these things a try and see if it gets any better...I'll update once I know more.
Thanks!
