Most times an action won't "degrade" properly is if you are using functionality available only in the higher version. You also have to be mindful of "how" you call up the routine (keystroke shortcuts, menu pull-downs, point-click...) Other than that, try it and see if it works. Test it by changing your "playback options" of your actions to Step-by-Step and that will let you know where it toss's it cookies...
