I am getting an unwanted margin down the whole right hand side of the website, this is happening on a number of the websites I am building with RFF, an example can be seen here omdwebsites.co.uk. On the desktop version there is no problem, the issue starts between the 640px and 1024px breakpoints. If you gradually reduce the browser width at around 940px you will see a scroll bar appear at the bottom and if you scroll to the right you will see a blank margin down the whole of the side of the website. This gets progressively wider until you reach the 640px breakpoint where it narrows but is still present. The fact that it occurs at 940px appears completely random, I do not have an additional breakpoint at this width. I have checked everything for padding/margins and there is nothing, mind you if it was associated with these then I would expect the problem to be evident at the 1024px breakpoint not at an arbitrary point midway.

I have looked at some of the examples others have posted on this forum and noticed that the same issue affects their layouts also, for example on http://the-heart-of-healing.com/ but at 1045px rather than 940px.

I know that it does not really effect the website operation but I am concerned that I do not appear to have proper control over the appearance of websites I am creating. Any guidance or solutions appreciated.

Hi Jeremy,
It's your navigation menu. It has a 960px width set with inline css.
Try removing it or setting it to 100%.

Superb, thanks Eric, you're a star! Probably the only thing I didn't check....doh!
