In IE9, to speed up diagrams, turn off "Display intranet sites in Compatibility View" under "Compatibility View Settings".  In my company environment, this setting is enabled by default.  I believe it is a default IE9 setting.  Anyhow, I was comparing why Firefox was faster than IE9 and stumbled across this setting.

Is there any reason I would want to leave it enabled for the Nevron Diagrams?

Thanks,
