Having complained about the new format problems with viewing the new banner on the iPad, tonight I have just started looking at FT on my MacBook Pro and now have a different problem. I suspect it is a "fix" for the original that now impacts on the other format!
The FT page just used to all load on the screen, but today the screen now goes outside the normal page load, and I have to manually scroll to get the right hand edge in view.
I assume that you have changed something on the other setting, which is now impacting on laptops too. I think you will get even more grumbles when they locate how to post on this forum
