jquery mobile custom icons greyed out

jquery mobile custom icons greyed out

Hi,  I've produced a simple set of web pages using custom icons in the footer, see example at


When first loaded the icons appear correctly against a yellow background as expected. However - after browsing between the pages - and in particular after following a link to an external site and returning - the icons become greyed out.

I'd appreciate any pointers to what I might be doing wrong.

Thanks Kirby

Correct



Wrong - Greyed out
