I dont think it is the CSS as its generating bulletpoint tags!
However, the only thing i can think of is x-tree-root-ct which doesnt exist, but not really the problem.
Code:
<div id="tree" class="x-layout-active-content">
<div id="folders-tb" style="width: 198px;">
</div>
<div id="folders" class="x-tree" style="overflow: auto; width: 198px; height: 502px;">
<ul id="ext-gen30" class="x-tree-root-ct x-tree-lines">
<li class="x-tree-node">
<div id="extdd-1" class="x-tree-node-el x-tree-node-expanded x-tree-selected">
<span class="x-tree-node-indent"/>
<img id="ext-gen45" class="x-tree-ec-icon x-tree-elbow-end-minus" src="/dhtml/ext/images/default/s.gif"/>
<img id="ext-gen42" class="x-tree-node-icon" unselectable="on" src="/dhtml/ext/images/default/s.gif"/>
<a id="ext-gen39" tabindex="1" href="#" hidefocus="on">
</a>
</div>
<ul id="ext-gen210" class="x-tree-node-ct" style="visibility: visible; position: static; display: block; left: auto; top: auto; z-index: auto;">
</ul>
</li>
</ul>
</div>
</div>
What you think? Why would it generate bulletpoints?!
