Just wanted to let you know that I fixed the problem (since DAZ closed the bug file without resolving it, saying they were aware of the problem and addressing it.).  I uninstalled Carrara and reinstalled the original Carrara 6.0 and the 6.02 update only.  Now everything works just fine, so it was something in the 6.03 release that was screwing me up.
I'll be leaving it at 6.02 for a long time, thank you very much!
