Ok,firstly it might be at my end - I'm at work, where we have to use IE as our browser.  
But I'm getting quite a few error messages.  For instance I clicked 'train' a moment ago and instead of training happening I got a message saying something like 'that didn't work.  There is probably a bug in your browser.  Don't stress, just try again.'
But I had in the same run of fighting a message saying 'url not found' twice and when I first logged in a message saying 'email submitted but not required'.  
There were others but I didn't really take much notice, just backed up a page and started again.
Like I said, it might just be me and IE.  But I thought I'd post incase it's a problem.
Now, I'll get back onto my campaign of trying to persuade work to use FF.....
