huhu .. thanks both for those fast answers ...
I found out that i could mae it work myself doing 2 things :
in the JSCookMenu.js, line 723
replace
obj.style.visibility = "hidden";
with
obj.style.visibility = "visible";
on the template file, in the "embed" tag ad
wmode="transparent"
in the "object" tag ad
<PARAM NAME="wmode" VALUE="transparent">
(this was better for me eyzeberg as i have absolutly no clue about flash

)
anyway ... hope this helps future "strugglers" with jscook & flash ...
Once again thank you all
