I figured out a solution. In case anyone is wondering, I turned off the logo in the theme options of the dashboard and made it background image in the main container for the logo area (A table!–this is a table based layout… is that old-fashioned or is there a purpose for it?). Then I used CSS to position the background image and tagline…
Anyway, to avoid IE hell, don’t use negative settings on margins or text indent!
Cheers
