Maybe I have to rephrase that note, but Flash objects and some scripts might conflict with your settings. On the other hand; the intended public is well aware of thos things because they visit sites with that kind of content often.
Although there are not many sites with such warnings (but there still are some), I think it's fair to inform the user. I do it (less obvious) on my site on-line too.
...but Gary...what about the overall design?
