I discovered a stack I made wasn't really saving when running under 
Dreamcard Player and wrote:

Yes, that was it. When I bring up Dreamcard Player, the RevOnline 
browser appears, and sure enough there is a Rev icon at the top right, 
with no rollover message nor any indication that it is a button, or 
that it actually has nothing to do with RevOnline, but is actually your 
access to the Preferences for the Player application! Jeezy Peezy! I 
checked the "Run in insecure mode" checkbox, quit and restarted, and 
now my little stack saves correctly in the player.

Thanks for telling me about this, Alex. I just spent a frustrating hour 
looking for this information: at the Dreamcard homepage there is 
nothing but marketing-speak -- "Do anything!". At RevOnline, I don't 
see the Learning Center in my channels (?!) so I didn't check there. I 
reread the readme files in my Rev 2.5 distribution for info about 
Dreamcard -- "Straight out of the box, Dreamcard provides the features 
of a word processor, a presentation tool, a simple spreadsheet...". And 
finally I looked again in the Rev documentation -- in Topics, 
Dictionary, and FAQ you can only get "dre" into the filter box before 
you get the annoying "nothing matches" dialog. Sigh and double-sigh.

Thanks for the warning about this!

Thanks so much for your help Alex. By the way, where is the info about 
secure mode?
