My website uses many applets which work well:
http://www.ac-noumea.nc/maths/polyhedr/index_.htm
There is an applet on this entry page (small dodecahedron on the left).
Since the last Java update (to version 7_25 on Win7 starter) applets
refuses to start on my local version of the site. The Java console
displays:
Exception in thread "Thread-45" java.security.
AccessControlException: access denied ("java.io.FilePermission"
"D:\Web_site\polyhedr\live\dodeca.m" "read")

Why does the same applet have a security problem when it is loaded from my
HHD and not when it is loaded from the internet?
Any idea to cure this strange behaviour?
