Time between Mildrop Presets

[Norwood]

Here's what I have set.

However, after about 5 seconds, Milkdrop changes to the next preset.

What on Earth am I missing?

Moved to MilkDrop forum.

You've probably enabled that the presets automatically change every few seconds.
If you use Winamp Modern or Bento, you can find a random button in the vis window, which can be used to turn the function off.

For classic or all other skins, simply use the Num Lock key on your keyboard to turn it off.
