My mistake .. I should have said that when you click on the tiles, a dotted border appears.  Container is #flashcontent and border already set to none. Using Firefox 7.  Developer toolbar refers #flashContent > embed#viewer but I can find no reference for #viewer in html or css.  Adding #viewer border:none to css .. still showing dotted border.

Thanks for your reply

No dotted border visible with actual Opera, too.

Maybe you should make a screenshot and post a link to it here, so we can see what you mean?

BTW:
As Steven Speirs wrote above, the reason for the dotted border could be your Firefox-add-ons.

The easiest way to test your "pure" gallery (with Firefox or Opera without any add-ons) is just a *portable* Firefox or Opera on your USB-Stick from http://portableapps.com/news ;-)

Firefox 7.0.1:

Firefox 8.0 Beta 5:

Opera 11.52:

Edit added three links to *portable* browsers ;-)

In your 'tiltviewer.css' file, you currently have the following:

#flashcontent {
    width:64em;
    margin:0 auto;
/*    height: 100%;*/
    padding:0;
    border:none;}

Try changing this to:

#flashcontent {
    width:64em;
    margin:0 auto;
/*    height: 100%;*/
    padding:0;
    border-style: none;
    border-width: 0;
    border-color: #000000;
}

If setting border-style to 'none' and border-width to '0' does not help, then setting border color to '#000000' should at least hide the border (as it should then be the same color as the background of your page).

This is a common issue for Flash content. Use this CSS to fix it:

#flashcontent {
      outline:none;
}
