Most of the time it sits at the centre of the screen but every now and then it leaps (is it a bird? is it a plane? No, it's superbouncyprogressbarman!) to the cursor position - and then back. All a bit travel-sickness inducing really. Clearly there's no very good reason for a UI element to do this dance of flickeriness.

Wild guess - make it ignore new positions coming via the route that tries to open a progressbar when one is already open. It ought to be possible to manually drag it around though.

I really don't know a solid answer for this, but it certainly isn't a good thing to have a 'do you want to do this important thing or not?' dialogue hidden behind a progress bar that is waiting for the user to answer!

The problem with sticking progress bar there is that we have the stacking of bars as sub-loads start. I don't think that would fit too cleanly into the dock. At least, not the way we do it now; perhaps one could collapse the prior bar into a single char sized icon and add the new bar, then obviously, reverse that as bars finish and return up the stack.
