You need to make absolutely sure you're talking about JavaScript and not just Java, because the two are entirely different beasts, and the answer would vary greatly depending on which it is.
For some reason pages will not allow javascript to run even though I changed the settings to enable. Does anyone else have this problem? Any help would be appreciated.
