Eliminated the bug with nulls, and it works perfectly fine across the network now. Try it back on localhost, and it's doing the same damned thing. So I track it down and find precisely where the problem is, except I can't find what the problem is. I know it's with an AJAX call, and by using dummy calls and stuff, I can prove everything works individually. Put it all together and I get the bloody 'Operation aborted' again. :'(
