Need help with visual basic webbrowser control

Hi all,

I have made an automated blog commentor, it is working nicely apart from one problem - on some blogs it sumbits the details and I get the 'Saving the comment' image comes up, that will then stay on the page until the end of time and never return back that its submited it.

Now, if i load the url in a normal web browser and try to submit the exact same details (name,email, url, comment) then it submits straight away leading me to believe that this is a problem with the web browser control.

Anybody come across this before and has a solution?

Thanks.
