UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Snow falling

Still one question though..

When I set the snowdistance on windowheight, the flakes top falling after one page; so they do never reach the lower topics. When using pageheight, I get the row of flakes at the top.
Is there a way to combine those two?

// Configure how much snow should drop down before fading ("windowheight" or "pageheight")
var snowdistance = "windowheight";
