ExtJS 4.2 bug

[nicetip]

After upgrading extjs to 4.2 version, close button disapeared.

So I patched BoxSelect.js like this.

< '<li class="x-boxselect-item ',

> '<li class="x-boxselect-item x-tab-default',

Drop down list needs tweaking as well. For now, using:
.x-boundlist-list-ct > ul {
-webkit-padding-start: 1px;
-webkit-margin-before: 1px;
-webkit-margin-after: 1px;
-webkit-padding-end: 1px;
list-style-type: none;
}
