Create New Template Identical To the one u are using now
so that nothing happens to your default
And play around with it

I suggest Going to Style Manager and click Go on the Template you created
Ctrl + F for #ffffff which is the color of the border you are trying to remove
Basically try to change colors of words like frame, border, surround
After you found the Solution, Go to you default Template and apply it there.

I hope this help, coz I have no idea how exactly to change the border colors
and just to let you know, my border color is different then yours
Thats why I tought it might be at the style manager settings

Cheers.
