...banning active scripts in listings? I'm going to assume it doesn't, for now, and switch to the static window (or no window). But it would be good to hear from one of the Auctiva folks on this. Thanks.

Yes. We've known about this for a while now and it will work within eBay's new method for active content.

So there is no need to be concerned that eBay may eliminate other checkout methods? I like auctiva, and I hope eBay does not have plans to eliminate the use of auctiva.
