Summertop: If there is another computer at your work, can you try that?

Why I say that is that it will narrow down if the problem is with your network (problem with all computers at work), or just your computer (if it works with other computers at work)

Other then that - I'm not sure. Sounds like it does what you want (like a post), but when the page then gives the browner the re-direct to another page - it stops there. My obvious question would be if there was any thing new loaded on the PC.
