I have several drop shadow styles saved in Photoshop CS2. These saved styles keep changing their attributes Is there any way to lock these down after they're created?

For example, I save a dshadow preset with Distance = 5 and Size = 5. Later on, maybe an hour, day, or month later the preset will apply with Distance = anything else and Size = anything else.

I'm usually able to use the saved preset hundreds of times before this happens. I'm sure this has something to do with resizing other content but I can't figure out how to stop this, or why it would apply to the saved presets when they haven't been applied to the layer that was resized.

Thanks,
