Thanks to everyone who replied, The problem seems to have been solved - at least for now...
I had asked the client yesterday to try and reburn the cd-rom from her mac, to see if maybe something had gone wrong with the burning process. As I mentioned, the last cd-rom I sent her was working fine. She hadn't come back to me about that, and even sent me an annoyed email that had no mention of it. So I was fairly sure that failed. So Just now I called her to get some more info and talk her through a test that would see if Robin's theory about the swfs was the cause of the problem (although I do check for initialization, something might have slipped through on a slower system)... And she says "Oh yeah, I reburnt the cd-rom on the mac and it's working just fine on the pc". Grrr... Clients! Thanks!
