Mouse cursor loses objects while dragging in Zoom

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to zoom using the mousewheel
2. Click any of the object for dragging
3. The Mouse cursor goes far beyond the objects

What is the expected output? What do you see instead?
The object should go with the cursor while dragging, like here: 
http://www.cyberz.org/projects/SVGPan/tiger.svg 

What version of the product are you using? On what operating system?
SVGPan library 1.2.2; 

Please provide any additional information below.
I've used all the latest SVGPan codes but the problem still remains

See the attached file below how cursor goes far from the objects while dragging.

You can see clearly on attached jpeg I've selected one pivot and while dragging 
it to right the cursor goes far from the objects and eventually objects move 
proportionately slow to the cursor..
