[jQuery] flickering side effect in IE 7

[brwalias]

I am experiencing flickering side effect in IE 7 when running this
pretty simple show/hide div script.  i'm hovering over an element and
moving the mouse into the div that expands during the show state.  The
flicker side effect is noticed when the mouse moves from the navTabId
to the dropDownId div.  There is a 1/2 second point where the
dropDownId div just disappears and reappears.

here is my script:

$(document).ready(function() {
var dropDownId = "#gssMenuRMAdminDropDown";
var navTabId = "#zz1_TopNavigationMenun6";
//happens on mouseover or click
$(navTabId).mouseover(function(){  $(dropDownId).show(); return
false; });
$(navTabId).mouseout(function(){  $(dropDownId)..hide(); });
$(dropDownId).mouseover(function(){  $(dropDownId).show(); return
false;});
$(dropDownId).mouseout(function(){  $(dropDownId).hide();});
});

I'm interested to know if anyone can duplicate the same problem and
help me fix this.

Thanks in advance.
