Customized Google Search Engine Hangs

[Trish]

I've tried creating a number of customized Google search engines and
managing them with different browsers (!Firefox, Opera, Avant, and
IE7). In all cases, javascript is enabled, but I get the following
errors. I have no ideas as a USER how to workaround this problem in
Google; and the Google support group has come up with no ideas. Any
suggestions?
