Next and back buttons hidden

Hello,

The Next and Back buttons have hidden themselves on my form, they appear with mouse-over. I have selected them as 'visible' in the page break properties, do you know why this is happening?

many thanks

Ah don't worry about it - it was the colour scheme. The background was covering the next button! that's dumb, maybe you should fix that.

But don't know how to delete my question, sorry
