Our USA-based company uses Postini (not through Google Apps but separately) via Windows XP SP3 Pro client PC's. A particular employee receives rich-formatted HTML documents. When he clicks on the Postini daily spam subject of a false positive, his Internet Explorer automatically logs into Postini and attempts to show him the message in HTML format (which works on my PC). However, his Internet Explorer (version 8) freezes. Last week, I thought I had resolved the problem by deleting his temporary files, rebooting the computer, and trying again (which opened) but this morning he called saying the same issue is happening again. He wants this fixed. Thoughts? Unfortunately, alternate browsers are not an option in this case.
