Strange black boxes around icons in Gecko based browser

[aweirig]

Hello,

when using roundcube 0.2 stable in a Gecko based browser on Mac OS X (Firefox 3 or Camino) or Firefox 3 on Windows I see strange black boxers around the icons in the task bar...



I don't see those boxes when using Safari or Opera on Mac OS X.

Is this a known problem?

How can one make those boxes "disappear"? I suppose it must be related to some CSS "misinterpretation".

Thanks in advance for your support.

Kind regards

Alex

Adjust common.css:

img
{
behavior: url('skins/default/pngbehavior.htc');
border: 0;
}

And remove you cache/temporary files
