Hi Mikey, and thanks for coming back to me so quickly.
There is a js column overlay on the page, (top right to activate).
If I open the page in chrome and press f12, to debug, I hover over the body tag and it shows me the values I posted earlier.
Maybe I'm being thick here and not reading it right, (quite likely), but I can't get my head around it
If I take a screendump of the browser window and paste it into photoshop, the image width (if you add the scrollbar) is about what you expect.
Attached is a copy of the screendump, with the page width and css highlighted.
- btw glad it looks ok on a tablet.
