i believe it is already the intention of this group to implement the 
intended extensions using behavioral technology on a microsoft platform.

there are some implementation issues with dhtml behaviors.

* path problems
URLs of behaviors are *always* relative to the containing (x)html page 
not the CSS file. very annoying.

* server problems
some server configurations mangle HTC files. also annoying but can 
usually be fixed.

* caching
not sure how explorer caches behaviors. but i'm sure it's not pretty.

* memory leaks
i've been assured that behaviors leak memory. apparently *all* explorer 
apps leak memory (due to poor js model)

* crashes
yep. behaviors crash the browser like nothing else. this is most common 
in testing phases (see caching above). from what i know this affects 
particular builds of explorer more than others.

other than that i can only agree that behaviors are the way to go!

hope that the group finds this information useful (and not too depressing).
