N800 can't submit transactions - session expired

[SHR]

I've spent a week discovering my new Nokia N800. Its very sweet, and (after updating to OS2008) it does pretty much everything that I want...except...

On some sites I cannot complete transactions. For example on a share dealing website I can login and browse the pages, but when I click "buy" I get logged out (session expired) and redirected to the login page.

Any idea what could cause this problem? and is there a fix?

thanks

Maybe cookies?

I have cookies enabled, and I can't see what else I can do to change the settings.

Has nobody else had problems with submitting transactions?!
