Good day!

I'm currently workin on a project whereby the background of the body is set to a photograph using CSS. 

background:url(BG.jpg) fixed no-repeat center 50%;

I have then setup a header pane, and some content ones - which use a semi-transparent PNG image to pride a background to the panes whilst still being somewhat see through in order to see the background image of the body.  This works well when viewing the site as a visitor - i.e. not logged into DotNetNuke.  The trouble seems to come when I log in.  Once logged in the PNG backgrounds are not rendered correctly, they almost disappear - the top left of each pane you can see there is a PNG set as the background, but then fades and disappears.  The PNG is a 1px x 1px image with transparancy set to 60%. And is set to the background of a pane (div) using the following CSS:

background:url(BGTrans.png) repeat;

I attach an example of what I mean to this post, does anyone know what could be causing this behaviour?
