Hi all, I'm trying to use DualListField in my project, but a strange problem happens.
All icon buttons appear too small.
Using firebug I've noticed that to the div button are applied several css style.
In particular this one from IconButton style:
com-sencha-gxt-theme-base-client-button-IconButtonDefaultAppearance-IconButtonStyle-button {
    background-repeat: no-repeat;
    cursor: pointer;
    height: 15px;
    margin-left: 2px;
    overflow: hidden;
    width: 15px;
and this from DualListField style:
com-sencha-gxt-theme-base-client-field-DualListFieldDefaultAppearance-DualListFieldStyle-up {
    background: url("data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAlElEQVR42q3TwQqCUBCFYV/rgo/lA0obcdMyRBKzgkQRw1CjTaYyh9QZhFHhczMz/+5aVv/ZzleFjpv2ozJGfr9X/VZB4FnVKgjkRaWCQJqVKgjcHjnLGDOQ5ghcrukCHRNuB4Eovk/Mj8l8D4HwnIB0TP53ETgFMYuOpDkC7sFnUUCaI+D5RxYFpPlqYM1OgY3PuQP90PG5qhW2VQAAAABJRU5ErkJggg==") no-repeat scroll 0 0 transparent;
    height: 16px;
    overflow: hidden;
    width: 16px;
The problem is that ,in Ext GWT Explorer example DualList style override IconButton style, unlike in my application the opposite happens, so the div have a size of 15x15 px and icons looks cutted.

How can this happen? I'm using gwt 2.0.5 and GXT 3.0.2
