I am getting ready to start delivering different .js files depending on the browser version ie those > 4.9 and < 4.9.
Once I have done that I can test for objects and react with in each script.
The only problems I have found so far.. If I am using a function for the new browsers that the old don't understand I have to put a blank function in the older version .js file. I have also found that when testing for objects Opera will return True when it really dosen't exist as a working object. (I am assuming the next version will turn these objects on)
Does any one see any additional problems with going in this direction?
