Jumpgate coordinate expansion doesn't work in Opera
The expansion of the jumpgate coordinates into a flat table (an excellent idea, BTW) doesn't work correctly in Opera. That's definitely true for version 1.62.6 (tested) and is probably true for all previous versions that have this feature, too.
The problem is that the first moon on the list in the drop listbox is still selected - instead of the empty element in that listbox that is added by the script.
The fix is obvious but you can't fix it yourselves, because the Origin morons have obfuscated the code of the script. It is just as I predicted - the obfuscation doesn't prevent me from reading the script; it only prevents you from fixing the bugs in it.
