...anyone else has experienced problems posting in Undercroft groups...I have discovered that I have to double-click the "post" button to successfully post, when I use my work computer. I have no idea why I do not have to do this at home.
Even now, I have to double-click. SO, if you cannot post in the groups, try double-clicking before reporting a problem...just a suggestion.

The key would be to find out the difference between your home and work computers. Are they running different browsers? Different Browser Versions? Different Operating systems? With that information we may be able to track down the difference.

Oddly enough, I use XP both at home and work...and browse with Opera.
To be honest, as long as I know how to handle it at my end, I can deal with it.
Other difference is that I cannot listen to my uploaded music at work either.
My suspicion is that the culprit is this damn filtering system they have implimented at work. I am constantly warned that these sites MAY contain objectionable material. It totally blocks the Lifeforce forum. I can use an anonymizer to read posts, but cannot post there.

So, I believe that seems the obvious issue.

Opera is a cross-interface browser. Unfortunately it can't read access keys clearly through a pre-defined script that uses some AJAX features. If the input type button has a defined accesskey..



...then Opera might not be able to read it. Access keys can be used instead of needing to handle the request of physically clicking on a submit button -- you could just press Alt + [x] to submit the form data.

But as you've pointed out, it could be a content filtering system that your work has installed.
