recalc bug when site change height

[BartekWolv]

When I load next posts in my tumblr, then sticked sidebar are moved to the bottom of page and stay there.

When I use recalc then sidebar back to work, but recalc reloaded this sidebar.

If I want put in to sidebar music player, then it be loaded every time, when I recalc sidebar.

It is possible to use silent recalc? Without reload sidebar?

Here is link to my blog: http://blog.isvn.pl/ You must scroll to bottom and click "AUTO" button, to turn on auto loading next post (then sidebar are bugged).
