[Laszlo-user] suggestions for tracking down source of INFO message in pagan-deities?

[P T Withington]

What this warning is telling you is that in 3.x when you defined a  
user class (e.g., `<class name="menu">`) we would define it globally.   
If you wanted to instantiate that class from script, you would say  
`new menu`.  For backwards compatibility, in 4.x we still define the  
global if it does not conflict with a built-in (runtime) class.  (We  
don't want to clobber globals in the different runtimes, e.g., in  
DHTML there is already a global class named `menu`.)  In the case  
where we don't define the global, we are emitting this warning, to  
remind you that if you want to instantiate the user-defined class from  
script, you need to say `new lz.menu` now.

Perhaps we should just do away with this warning and rely on  
documentation instead?
