Are you using a non-default wmode?
It is set to "opaque", which I think is the default.
That is not the default. Remove any wmode setting and see if you still have
Wow ... wow... Magic. Your last suggestion of removing the wmode attribute worked. The page looks great. The scroll works flawlessly where before it mangled the child controls on the page making it look like a hurricane scene.
The html was originally set with wmode as "opaque". I tried changing it to "transparent" after your first response, but this made no difference. What fixed the problem was removing the wmode attribute altogether.
We've built a rather large application. Is there anything we need to be aware of, or anything we need to look out for by removing the wmode setting?
Flash Player does not always work well with non-default WMODEs. The WMODEs
allow you to overlay HTML content with flash content and vice-versa so as
long as your app doesn't need to do that you should be fine.
