Logic, error handeling (or what ever you would call it)

I have come unstuck many times in WD by selecting options that conflict or contradict eachother. When I come here to get help, I am told “you can use both settings” etc… as with the webcam all day movie wmv and flash issue that I had recently. Windy told me that I can only use one or the other. That’s just one example. It would be good if in situations like that, if you select one, the other would be greyed out, or at least a message to say you can only use one or the other.

for the example given, I will add the words, use .swf instead
