opening 2 pages with 1 link

Hi there,

I got a frameset existing of a top frame (logo), a left frame (navigation)
and how surprising.... a right frame for the content.

Within Dreamweaver, I used the simple flash button "glass silver"
When clicking the button, i'd like to open a text in the right frame, while
another page in the left frame also opens.....

is there an easy way for this one?

thnx.
