I can't reproduce this.  Maybe this is a Windoze-only bug, or it's
fixed in the current CVS.

(On GNU/Linux, there is a different frame movement bug, which was
previously discussed on this list, that's not caused by Emacs but by
the Metacity window manager [apparently the latest version of Metacity
doesn't like programs to specify window positions; other window
managers work OK].)
