FYI - we installed FireFox on one of the problem PCs, and although there
were some funky formatting issues, the Infragistics WebCombos worked, so
this seems to point to a browser setting or something IE-related. We check
all the security settings and did everything we could there, we thought....
Any other ideas on what setting we could be missing? Don't know if this
could affect what things we need to check, but it is a HTTPS site.

Thanks!
