Running and running properly are two different things. Would you want to take a chance with a product that does what DW does?
As I said, "Naaah", but on the other hand, I'm not 100% certain that there'd be any risk involved if I didn't go past Preview, in which case DW wouldn't actually be doing what it does (if, as I believe, its first pass is no more than a read).
I dunno, I'll think about taking a shot with a clone to see what happens, but my DW disc went bad, and I'm not sure I can run the app under any circumstances.
(The poster who ran it wasn't even aware that it wasn't supported despite his adamantly proactive attitude towards app updates/grades; I was just reporting that he did, and with no apparent repercussions.)
