I am working with one of his libraries,
specifically with gxt(gxt-3.0.0-rc.jar, gxt-chart-3.0.0-rc.jar and gxt-legacy-3.0.0-rc.jar) and I had problems using the Grid class.

The specific problem is due after the change of library (of gxt-3.0.0-beta4.jar togxt-3.0.0-rc.jar) as the icon in the header of each column is not displayed correctly:

- In IE7 and IE8 menu appears only on the header text and not in the rest. The click of the sort only works on this text.
- In chrome and firefox do not see the menu, and click the order does not work.
