A sequence of DLL/Control re-registration to clear up javascript errors in all the OrganizationDesigner popups.
I had a lot of problems with javascript errors in Org Designer. I was able to fix them by re-registering some IE controls and libraries. In doing so I have cleared up all my javascript errors. Here is the sequence - hopefully it helps others.
open a command window and type the following:
regsvr32 msscript.ocx
regsvr32 dispex.dll
regsvr32 vbscript.dll
