alchymyth- thanks for taking the time to look at that for me- you’ve nailed it!
Problem:Solved
Thank you.
esmi- thanks for your suggestion, I have tried a similar exercise using ‘inspect element’ function within Google Chrome but just can’t seem to locate where the problem lies. I’ll have a go with Firefox/Firebug as you suggest later.
JPLC- thank you for your suggestion too, it would work but also means that if the browser is minimised to less than 1000px (I’ve set min-width to 1000px) the scrollbas don’t appear and therefore navigation is impossible!
More suggestions welcome from the floor……….
