drag and drop fails in manager after scrolling the window in Firefox

Hello community,

I have recently noticed this strange effect:
In the manager home site are these sortable boxes. You can change their positions by drag and drop.
This works fine until you scroll down the window in Firefox. After that, the drag and drop functionality fails. This problem is on every draggable item and it looks like Firefox (or extJS) does not update the coordinates of these items after scrolling the window.

This happens in MODx Revolution 2.0.6-pl and Firefox 3.6.13 / 3.6.15

Is anyone able to reproduce this?

Greetings
Sascha

PS: Same thing if I expand the elements object tree, scroll down the window and wants to add a new category by rightclick "categories". The context menu appears at a position somewhere above - maybe where it should be if I have not scrolled the window.

+1 here. No matter which Revo or FF version, the problem also resists in 2.0.8 and in FF 4. For a comparison look at this extJS 3.3 demo:

If you open some folders and then scroll down in FF, the drag&drop functionality is okay. If you do the same in MODx manager the coordinates of the element to be dragged are kind of lost (sometimes you see the tooltip several pixels above the dragged element).

I notice this in FF, Safari and Chrome. Hopefully there’s already a bug report.
