Cannot Scroll to The Last Column of a List Grid with a Large Set of Fields on IE 9

[chatchawee.tangsayan]

Issue Details:
After populating data, the grid with a large set of fields cannot be scrolled to the last column on Internet Explorer 9. This happens on both Smart GWT 2.5 and 3.0p. The issue can be replicated using the below test case, and click the populate button when the horizontal scroll bar is located at the leftmost position.

My Test Environments:
GWT 2.3.0
Smart GWT 3.0p (http://www.smartclient.com/builds/Sm...GPL/2012-01-16)
Smart GWT 2.5 (http://code.google.com/p/smartgwt/do...5.zip&can=2&q=)
Test against compiled javascript files on Windows Internet Explorer 9.0.8112.16421, Update Versions 9.0.4
Windows 7 Ultimate Service Pack 1
