Is it just me or is there a problem with access to the HMRC web site ??
It was me !!
I've never had this before but apparently if I logged into an account and didn't log out properly the web site will default back to that section. The answer ( from the help desk - yes very helpful) is just to keep logging out until the computer gets back to the browser.
I live and learn - still !!
It could be just you Bernard. I've just been (16.00) on the self-assessment section, with no apparent problems.
