draggables with position: fixed "jump" if the page is scrolled (in ff2)

[tmm1]

if you scroll down on a page with a draggable position:fixed element, and start dragging the element, it will jump down (as soon as you pick it up) by whatever amount the page is scrolled

Also seeing various other strange issues- the scrollbar to the right of the draggable div is unusable, and the entire page has strange "glitches" to the right of the draggable as you move it around. Safari has no issues, only FF2 has problems. My DOM looks like:

<div id="windows">

<div id="window_1" style="position: fixed"></div>

</div>

<div id="content">

stuff

</div>

Also in ff2 (with the latest jquery release), the portion of the page's scrollbar directly to the right of the draggable will show display artifacts and refuse to respond to click events. This appears to be related to the latest jquery, as it happens with older jquery-ui releases coupled with the latest jquery 1.2.6 as well.
