If someone knows a better way to get IE to co-operate with this set up, I'd appreciate the help. An acceptable alternative would be to only create one iframe at a time (which IE can handle), by using a link to trigger the iframe creation. I just can't figure out how to get that to work.
The cross domain resizer uses the frame manager trick, the rest is homespun.
Thanks for responding. Unfortunately we can't use php or any kind of server side scripting with this particular project. Iframes do the job and you can see in Firefox the iframe id's and sizes being run in the address bar, but IE gets stuck and just bounces between two id's endlessly and never completes the resize script. It works fine with only one iframe but that's not an option, unless we use a link to create and resize one iframe at a time.
I should add we have access to the source site.
