richfaces 4: unable to select from h:selectOneMenu embedded in rich:collapsiblePanel on windows xp
===

<b>
I have a **h:selectOneMenu** embedded in a **rich:collapsiblePanel** header.

Using the app on mac osx (10.6.8, chrome or safari) everything works as expected, i can select an item.

Under windows xp (chrome, ie, firefox) things get mixed up.<br>
Obviously the **'hosting'** rich:collapsiblePanel gets the mouse event as well when trying so select an item out of the h:selectOneMenu, which results in being unable to make a selection.

*Here are the relevant code snippets:*<br>

`<rich:collapsiblePanel id="genericFilterPanel" switchType="ajax" 
    expanded="false"
    toggleListener="#{paramBean.filter.handleToggle()}"`         
        
`	    <!-- filter -->
		<h:selectOneMenu 
			value="#{paramBean.filter.filter}" style="width:200px"
			converter="#{paramBean.filter.converter}">
			<f:selectItem itemLabel="" itemValue="" />
			<f:selectItems value="#{paramBean.filter.converter.listItems}" 
				var="item" itemValue="#{item}" itemLabel="#{item.name}"/>
			<f:ajax event="change" execute="@this" render="genericFilterPanel" 
				listener="#{paramBean.filter.filterSelectionChanged()}"/>  	
		</h:selectOneMenu>
`



I appreciate any help<br>
