Today, when you use ExtJS 2.2.1 for page development, you find that the header of the grid in IE6 displays an exception, and the icons and text are garbled, as shown in the figure:

　

In Firefox and Chrome display are normal, very strange, is it a version of the problem?

Comparing the 2.2 version and the 2.2.1 version of the EXT-ALL.CSS, we found that there are two different, and after the 2.2 version, everything is OK:

Find. X-menu a.x-menu-item{display:block;line-height:16px;padding:3px 21px 3px 27px;

Modified into. X-menu a.x-menu-item{display:block;line-height:16px;padding:3px 21px 3px 3px;

Find. x-menu-item-icon{border:0 none;height:16px;padding:0;vertical-align:top;width:16px;position:absolute;left : 3px;top:3px;margin:0;

Modified into. x-menu-item-icon{border:0 none;height:16px;padding:0;vertical-align:top;width:16px;margin:0 8px 0 0;

In addition, ExtJS the latest 3.0 RC1 version has not been the problem.
