Both are courses of action that I would take assuming the info in the VC comments and/or the developer is still about. Sometimes that may not be the case. > Well Object is always THE base class.

There are some cases where creating a new class with properties is going to make sense, there other in where having the flexibility of Object make sense. You may not be aware there a big difference between Object and something that extends Object. Objects’s are dynamic and properties (and methods) can be added at runtime but this comes at a performance cost. Class that extend Object are not dynamic and you can’t do this and as a result are faster. > Justin - If you have clear performance results then please document them in > the wiki. Other people have already researched this and it’s well known AFAIK. For example here's an old article by Alex [1] where for accessing properties there’s a 20x performance increase. Obviously there’s a little more to it than just that but more recent article also have similar results. Object can be useful but it does come at a performance cost. > Thanks. Do you know how to deactivate useless rules? Yes. Thanks, Justin 1. http://blogs.adobe.com/aharui/2007/10/actionscript_readwrite_perform_1.html
