There seems to be a problem with the latest version of flash player.
I discovered this last night when upgrading the player. Some flash movies won't run under it.
Suggest you don't upgrade from older versions of flash player 9.
I see that other people have also reported problems with lastest version. Could be the way they have written programs but flash is supposed to be backward compitable as far as I'm aware.

found adobe issue expalining problem:
getURL and navigateToURL issues with Flash Player 9.0.115.0 ActiveX control
