Try switching to a steel string guitar and back - same problem! Though it is taking me less time now than it used to - I figure a couple of minutes and my fingers lock back in so it gets better with repetitions. I learned "Mad World" on the classical, but prefer it played on the steel string (not to mention I keep a steel string in drop D so I dont' have to keep retuning). And I have a feeling that my nylon strings would fall off if I retuned to my current obsession - Taro Patch (aka open F) tuning
