Richfaces tree drag and drop support

[krikorherlopian]

I have richfaces tree, where am using drag and drop.However the problem is on quick back to back button clicks, the mouse is being very sensitive and dragging/dropping.

How can I control mouse sensitivity?

<rich:tree    adviseNodeOpened="#{menu.adviseNodeOpened}"  ondrop="return mol(this)" dropListener="#{menu.processDrop}"
                                             nodeFace="#{treeNode.parent.parent == null ? 'node' : 'leaf'}"
                                              treeNodeVar="treeNode" dragIndicator="indicator"

                                    <h:outputText  value="#{item.objectName}"/>
                                    <a4j:support    event="oncomplete" reRender="bar1,mol1" />
                                </rich:treeNode>
                       
                                <rich:treeNode  ondrop="return mol(this);"   acceptedTypes="pic" type="leaf" dragType="pic">
                                <rich:dndParam name="label" value="#{item.objectName}" type="drag"></rich:dndParam>
                        <a4j:support     event="ondropend" reRender="bar,mol,panelGrid" action="#{menu.changeFormFalse}"  />
                                <a4j:support     event="oncomplete" reRender="bar,mol" />
                                <h:outputText  value="#{item.objectName}"/>
                            </rich:treeNode>

thats my code, if i click on two successive nodes quickly.its entering the ondrop function.

drop is happening so quickly.unlike the original on livedemo..
