[Dynapi-Dev] NS6 events and contentWH

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello all!

I recently revised the latest (CVS) version of events.js, and have events working properly in IE5, IE55, NS4, and NS6 (I don't have IE4, but I am almost positive that it will work in it).

It would be great if anyone would like to plug this into their version of the API and take it for a test drive! (Also, I would appriciate any feedback!)

Now, I made A LOT of modifications/optimizations, and I haven't commented everything, so please don't get angry for the lack of comments... ;-)

Here goes...

I have also made A LOT of modifications to dynlayer.js, which fixes some of the existing problems, including tge contentW/H (specifically in NS4 and NS6, in the createElement). But it is still undergoing evtensive testing.

I need to set up CVS on my computer, so that I can make these updates soon.
