Selection field no right click properties

I am not able to right click on a selection field (that is a drop down menu in forms) in Firefox (use to happen in 2 and it happens in 3, too). Right clicking on it is necessary in order to change its properties once it is first created! Also I cannot see if there is a way to "select" it and then hit the appropriate selection field button to invoke its dialog.

For instance put this code in FCK and try to edit the selection field's properties in Firefox by right clicking on it, selecting it or any other way:

<form name="test_form" action="no.php" method="post">
    <p>
        Check this: 
        <select name="test-selection">
            <option value="1">test1</option>
            <option value="2" selected="selected">test2</option>
            <option value="3">test3</option>
            <option value="4">test4</option>
        </select>
    </p>
    <p>Check that: <input type="text" name="text-field" size="15" /></p>
</form>
<p>OK then...</p>

So, am I missing something or is this a bug?
