Drop-down menu items appearing all over screen ?

Question

So i have a JSP webpage accessed by about 20 people. It has some drop-down fields for doing a search. After the search, the screen gets all messed up (this happens randomly and is hard to reproduce). It basically takes a drop-down menu's items and places them randomly across the screen.
I am not sure what is causing this, but if you have any ideas or suggestions, I will appriciate it. I am not posting any code yet, cuz i'm not sure where the problem is, or what it is?

Answer 1

The following is from the JSP where I feel the problem is occurring
   <%=XMLUtil.toString(XMLUtil.toHiddenField("pname",  qSearch + ": " + queue.getName()) )%>
    <TABLE class="TITLE_TOP">
        <TR><TD><%=queueMgr.getSelectionModeSpecifier(null)%></TD>
            <TD align=right><A class=BUTTON href="javascript:startSearch();" onmouseover="return setStatus();"><%=pm_logon.map(PMConstant.SEARCH_BTN)%></A></TD></TR></TABLE>
        <TABLE class=PANEL>
        <TR><TD class=LABEL><%=pm_logon.map(PMConstant.MSG_QUEUE)%></TD>
            <TD><%= XMLUtil.toString(queueMgr.getQueueIdSpecifier())%></TD></TR>
        <TR><TD class=LABEL><%=pm_logon.map(PMConstant.MSG_FILTER)%></TD>
            <TD><%= XMLUtil.toString(myFilter.getFilterCountSpecifier() ) %>
                <%=pm_logon.map(PMConstant.MSG_PAGESIZE)%><%= XMLUtil.toString(mySearch.getPageSizeSpecifier() ) %></TD></TR>
        <TR><TD></TD><TD><%= myFilter %></TD></TR></TABLE>
        <BR>
    <%
        if (size > 0) {
    %>
    <%=XMLUtil.toSummary(pm_logon, size, mySearch, "mySearch")%>
    <%= XMLUtil.toString(mySearch.getPage("editColumn", false, false, false, false, false, true)) %>
    <%
        }else if( SearchManager.ACTION_SEARCH.equals(mySearch.getSearchAction()) ){
    %>
         <%=XMLUtil.toWarning(pm_logon.map(PMConstant.MSG_NO_REC), pm_config.queueAutoRefreshInterval()<= 0 )%>
    <%
    %>the following is a method from the XMLUtil being called:
    public static String toString(Node node)
        StringWriter out = null;
        DOMWriter domWriter = null;
        String returnString = null;
        try
            out = new StringWriter();
            domWriter = new DOMWriter(out);
            domWriter.print(node);
            out.flush();
            returnString = out.toString();
        catch(Throwable e1)
            returnString =  "";
        finally
            try
                out.close();
            catch(Throwable e2)
        return returnString;
    }
