MaintainScrollPositionOnPostback line limitations

[Rosalind P.]

Hello

I have a very long aspx page that consists of several panels. I am using
MaintainScrollPositionOnPostback = "true" in the page directive and framework
3.5. The scroll position on postback is maintained properly as long as the
y-coordinate is not larger than 4000. Is there a limit on how large the
y-coordinate can be when using MaintainScrollPositionOnPostback?

Thanks,
Rosalind
