The only way I can think that you could hide the cross hairs and keep the curor window would be to create a shortcut or hotkey to toggle the cursor tracking off and on.
To assign a hotkey going to Tools --> Customize Keyboard.
a. Highlight Cursor.CurorTracking from the Commands List
b. Click on the Type New Shortcut Key field and press the desired key you want to use.
c. Click the Assign button to complete
