I have designed a page, which uses 5 frames:

the top, the left, the middle, the right, and the bottom frame.

All frames except the middle frame are independent of their size. (*)

The middle frame is fixes to a height of 620 and a width of 1022.

The page which is loaded into the middle frame contains also frames.

The advantage: the middle frame with all its content is always placed into the middle of the browser.

This is important if somebody has another screen resolution.

The problem: If this site is optimized for 1024 x 768 and somebody has a resolution with 800 x 600, or has the favorites bar enabled on the left site, then you will not see the whole part of the middle frame.

What I want is to enable scrollbars for up and down scrolling.

Scrollbars are not show even if I enable them for the right and the bottom frame.

Any ideas?
