Thanks for replying...
What I can't figure out is is was working fine before I sent it off for repair. Had even upgraded to v5.320 with no issues, and now this.
I was thinking I would try to go BACK to a previous software version, just to see what would happen, as long as it wouldn't "reboot" while I'm trying. I will mention that while messing with it, I got into a menu what I could only describe as a DOS looking menu...actually, not sure me messing with it did that or it just coincidentally appeared, but, the only way to get out was to power down...uuuuuuugh!
