In TIG 1.9f and TIG 2.3, the extract data source view is different.When you view extract data and then view the css source code, the overflow tag is set to hidden. They should not be visible unless the zoom level exceeds the page size and scrollbars are necessary to move around.
It works for 1.9f version of TIG in the same version of IE and does not work for TIG version 2.3 on same machine(same version of IE)
