Yes, thank you very much. But I'm afraid, by re-installing back the earlier alpha-4, I don't know how much rollback I'm on to the point that Nifty may perhaps not be quite updated. Because, while most of Nifty works, so far, I just couldn't load up the interesting styles for panel or effects like draggable, black-style panels or scrollbar yet -- they all don't seem to work -- but perhaps I've wrote wrongly in calling them up, maybe there are more codes to write to call them and make them function as they should be, I'm not so sure.
I was wondering, what's the proper way of calling up all these styles?
thank you, madjack lemme give it a shot at these. if nothing works, I’ll just play with the controlDefinition, control and basic interactive for the time being till I figure out what happens.
