loading an external page in a frame set looses the frame name

[fiuPikeOY]

Hello,

I have a frame set of about 6 frames. The center one called "content" is the one where all the content goes into. One of the links of the page loads an external page into that target called "content" but then when I click on any other link nothing happens as if the frame set lost the name of that particular target. I can hit the back button in the browser, and it will all start working again.

Any ideas why this is happening?

Thanks in advance
