If I knew that before, I had clearly forgotten. Thanks!!

Most definitely (add it to the FAQ). Your response and Brett's response
have been very helpful to me. Now, for Robert's question on right
aligning labels .... :-)
I'll have to play with this newly learned functionality. I'll also be
happy to start perusing your website, looking for possibly out-of-date
/View beta stuff. It'll serve as a nice reminder on /View basics, too!
Thanks.
