I'm having a problem with some machines that are unable to open up a window from a link in IE. We've recently updated our machines from IE6.0 to IE6.0SP1 and the problem has shown up on a couple of machines. We've tried to re-registry some DLL's, but that didn't work. I've found a temporary solution: elevate the user to a local administrator on their machine, but this can only be a short term fix (company policy). Any ideas??
