Multiple applets on same page freezes firefox

Hi,





We've recently upgraded our curator tool versions MarvinSketch from version 4 to version 5.1.1. However in some cases we require to have multiple applets open on the same page (sometimes 4 applets). This used to work with no problems in version 4 of MarvinSketch but it now freezes Firefox when I open a page with three applets running on the second time. This does not occur in IE or any other browser. The first time it runs with no problems the second time the third applet seems to freeze and does not display a toolbar or the molfile its just a grey box.





Any ideas what could be going wrong?





Cheers,


Paula








Below is an extract of the applet code I use:

<param name="autoscale" value="true" />


<param name="detach" value="hide" />


<!--<param name="menubar" value="false" />-->





<param name="mol" value="\
