Thanks Tim for letting me know about CSS3 resize I didn't know about that.

I would personally prefer jQuery over pure JavaScript but the company I'm currently contracting with won't allow any direct solutions like that cause they usually hire JSF/Java guys rather than JavaScript/jQuery ones. Also they are officially supporting IE so CSS3 is also out of question, that really sucks!!
Well I'm still playing with Framesets and jsf, see if they can be used together ;)
