I havent messed with external classes (since I am new to SQL), but they sound interesting and ...hmmm, safer.

Can you include all the methods and images that you get with ObjectManager? any good source of info on this?

Pretty sure you can do anything with external classes/methods that you can do with TTW ZClasses and methods, plus a whole lot more. Using a RDBMS is really a different way of looking at things. I have more experience using relational databases, so it feels more familiar and safer, but I do feel drawn to the whole object database paradigm. I am sure that for some applications it will be much cleaner, faster and easier. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
