Chrome locks up opening Unity web player

Chrome completely locks up to all input. The application isn't hung, but it does not respond to input. It seems to happen randomly. I have to force close Chrome in the task manager. When I try again, it usually works. This happens from me with my application as well as other Unity web apps I have seen on the net. Has anyone else experienced this problem? It's really not something that I want to force on my users. Could it be something in my code or just a problem with my Chrome installation?
