Macromedia AppletAce Image map question

I have been using Applet ace to create imagemap roolovers and links. All seems to work fine but the Netscape java console gives me the following error mesage everytime a roolover accours.

Warning: Thread.suspend() was called; Navigator deadlock might result


the following is the applet parameters in the html doc
(http ommited)

<applet code="ImageMap.class"  width="402" height="13" CODEBASE="http://***********/www.****.**/Java">
<param name="area7"         value="english,rect,../english/frameset.html,_parent,361,0,402,13,null,null,null,null">
<param name="area6"         value="map,rect,../roadmap/frameset.html,_parent,325,0,354,13,null,null,null,null">
<param name="area5"         value="job,rect,../job/frameset.html,_parent,266,0,317,13,null,null,null,null">
<param name="area4"         value="dialog,rect,../dialog/frameset.html,_parent,220,0,260,13,null,null,null,null">

<param name="area2"         value="output,rect,../output/frameset.html,_parent,99,0,140,13,null,null,null,null">

<param name="defaultDownEffect" value="replaceImage,down">
<param name="area1"         value="top,rect,../ontop/frameset.html,_parent,0,0,41,14,null,null,null,null">
<param name="image"         value="./pic/text1.gif">
<param name="defaultEnterEffect" value="replaceImage,enter">
<param name="enterImage"    value="../pic/text2.gif">
<param name="bgColor"       value="#083303">
<param name="downImage"     value="../pic/text3.gif">
<IMG SRC="./pic/text1.gif" ALIGN=MIDDLE WIDTH="402" HEIGHT="13" BORDER="0" USEMAP="#jvm">
</applet>

So please what to I need to do to get rid of this error message for I assume it means that the applet will eventually crash Netscape?

Thanks Fabio
