In my work environment where I frequently post I have firewalls and a proxy in place for security. Some recent changes have caused weird limits on posting. I can post short messages, generally 100 works or 256 characters or less, but anything longer fails. This happens everywhere, responding to discussions, messages, blogs, etc.

This happens with internet explorer 8, firefox 3 and chrome. Has anyone had similar issues?

bsc,
Are you seeing this on all sites or only on TuDiabetes?

Do you no longer see it when you are home?
Ok, I admit, I am seeing this on other sites (diabetesdaily for instance). I wasn't going to admit I actually visit the competition (altho David is on the board here, so I guess it really isn't the competition).

And I don't see this from home, that is why I believe it is related to the network here. And I did just upgrade to internet explorer 8 (I'm not sure any microsoft upgrade actually improves anything). And the problem only appeared after I foolishly upgraded, and it may or may not be related.
For what it's worth I recently upgraded to IE8 although I use FireFox. Everything still works.

I did have a problem on our server once after upgrading to an earlier version of IE. I was trying to download something in FireFox and it kept failing saying I had insufficient privilages. This made no sense as I was logged in with administrative privileges. It turns out FireFox gets it's security settings from IE. Since it was a server there are more stringent restrictions on downloading and I had to specifically allow downloads from that URL in IE. After this change FireFox downloaded the file. Not the same but maybe play with IE's security. Perhaps try another machine at work that hasn't upgraded to IE8?
I did have some problems with my certificates. I had to export them and re import them. I have tried adjusting the IE security settings. What makes me believe it is a underlying networking issue is that the same problem is present in IE, Firefox and Chrome. Most of the IE settings affect the application security, not the underlying internet networking security.
It does sound like something to do with the network you are on. I guess you could try talking with the person in charge of the network admin, but I am not sure you could create a good-enough case for why you should be able to access a social network from work. :)

And, indeed it's great that you also use DiabetesDaily: the more information, the better!
I doubt this has anything to do with your problem, but I am having more of a problem accessing websites since I upgraded to IE8. I have found that hitting the compatibility view button helps fix some of the problem but not all.
