With Xcos : bug (?) with one computer, but not on an other one

[Francois WEISS]

Hollo,
I am a new user of Scilab 5.3.2 for windows 32 bits.
I have seen few times related on web pages the problem below, but never 
solutions :
My problem is that a double-clic on Xcos bloc (or using the parameter menu) 
must open the parameter window of the block
This works fine on the computer with
win XP familly ed. SP3 ; proc. AMD semptron 1,8 Ghz ; ram : 448 Mo ;
(is installed : Java J2SE runtime environnement 5 update 4 ; and Java 6 
update 11).
but doesn't work on the computer with
win XP familly ed. SP3 ; proc. Intel core2 ; 2,13 Ghz ; ram : 2 Go ;
(is installed : Java DB 10.3.1.4  ; and  Java 6 update 25 )
The messages bollow are then prompted in the Scilab window :

What is wrong on the second computer ??
thanks for answer.
François WEISS
