my advice as a pro user of apple systems and technician regarding zoom is not to use  the window in window zoom. what happens is due to the use of the video manager in OS X, it copies the mouse overlay. the solution is to use zoom in full mode. a tip regarding this is to ensure the mouse is centred to screen so the mouse pointer moves the whole zoom field and no screen lag.

here's how this works:

in system preferences. go to accessibility. (if running the latest os X 10.8 build it is as follows)

in the accessibility window, the left tab shows speech, ZOOM, etc. go to the zoom tab.
in zoom. use the following  settings:

CHECKBOX CHECKED (depending on whether the user wishes to use keyboard shortcuts) Use keyboard shotcuts to zoom.
CHECKBOX CHECKED Use scroll gesture with modifier key (Control key by default)
CHECKBOX CHECKED smooth images.

Zoom Style: Full screen

In the more options window. activated by  pressing enter or clicking on "More options"
Checkbox unchecked: Show preview rectangle when zooming.
When zoomed in. the screen moves: 
Continuously with pointer. (button selected)

close accessibility and quit system preferences.
