I spent years doing business systems support for dell. I have allot of IT experience...Stareted with a military carrear supporting routers, and systems. Spent most of my life doing IT.
This is the 2 things it sounds like to me since the issue only happens at work. I think you are dealing with a network filter. You may be posting with words or content that are picked up and blocked by the filter. It may be a proxy, filtering all data to protect ďconfidential dataĒ from being sent out from the company.
Try a few posts at work to see if filtering words, or just any data. I donít think is and IE issue. I use IE exclusively because while I am an IT guy, I am to lazy to install Firefox on my own system. You know how it goes the auto mechanic is always the one with broke down car. I have never had issue with this site.
