Hi Kirk,
I've been out of town w/ no computer access.
Older on-line galleries do still show up - but only after I got a prompt while in Safari asking if I'd like to permanently use Flash to view all galleries (or something to this effect).
For some unexplainable reason, I put a "#" symbol in the gallery I was attempting to export. For grins, I removed the #, renamed a few files, created and uploaded a gallery. This did allow me to see the (new) gallery once I uploaded it to my site. But the offline gallery, and older galleries still do not show up on either Safari or Firefox. I downloaded PM5 and went through the same process with the same result - uploaded galleries work, off-line galleries do not.
I'd still love to have galleries open up in Safari after I create them... any suggestions appreciated.
