repositioned dynamics position doesn't save with file

I checked the issue tracker, but I didn't find anything that addresses this.

When you drag a dynamic from the palette to the score, it snaps to a default position. If you reposition the dynamic -- either by dragging, or by changing the X and/or Y settings in the Inspector -- the new position does not stick after the file is saved and re-opened. When reopened, the dynamic is back at its original default location.

I'm referring to the current nightly builds, obviously, and I use Windowx XP SP3.
