IE Beta 3 Lockups

Seems like every time I send a message in OWA, IE beta 3 locks up. I love IE, but these lock ups need to stop. To be fair, FireFox locks up on me occasionally too... but not nearly as much as this new IE build. If you are listening IE team, my biggest IE peeves have to be the lockups and the fact that the javascript debugging / error experience blows serious chunks. As AJAX gets more and more popular, people are going to prefer Mozilla more and more simply because it gives decent error messages and its javascript console's error log is far superior to IE's javascript error handling.

Related story... we were having lockups in IE 5.5/6 with a web app we were developing a while back. We replaced all the PNGs with GIFs and it seriously cut down the number of lockups. Other people seem to have encountered the same problem (http://blogs.msdn.com/venkatna/archive/2006/05/26/608341.aspx, http://blogs.freshlogicstudios.com/Posts/View.aspx?Id=74d242fe-2044-4020-8e84-0a178be5003d). Apparently, one possible cause is that IE uses an ActiveX control to render the image that locks up the browser when the URI for the image is incorrect.
