SmartNavigation on a frame page

[kolos]

Hi!

I had to face with a strange problem. A html page loads an aspx page
(written in C#, but I think it does not matter in this case) into one of the
frames on the page. I tried to use the SmartNavigation feature on the aspx
page to avoid the "flickering" and scrolling, because a dropdownlist do
postback. The result is very strange: when the page does the postback first
time, does not work the feature (the page jumps to the beggining), but after
this (2nd, 3rd, nth postback) everything fine.

???

Thanks in advance,
Kolos
