i found that, ....
when i open this by IE, the left frame content all go down to bottom part...
and when i click one of the link in left frame, the right frame displayed as full page....
but all this is worked well in firefox...

frame1 height is set to 1050px, Fx ignores this as there is no real content in empty.php
