I have Windows 98 in spanish and I believe I have also
the Java in spanish too.
When opening Jose, appear a Java error popup saying
lang.properties.es was not found. Apparently Jose dont
include such spanish language file in the config folder.
What I did was to add the extension .es to the english
lang.propeties and then all works OK.
Anyhow I artificially solved the problem, I suggest to
include an spanish lang.properties file.
