Random Slideshow is no so random...

First things first: thanks for this very useful module. Yoe made my day! (well, my frontpage indeed)

I create a slideshow for my frontpage pulling from 20 nodes. I would like to use random sort order for that 20 but I notice that it is not so random. Nodes are repeating very often before any other node comes to see, sometimes even they repeat after them selfs.

Is it possible to optimize the random feature so that it doesn't repeat an item that it was just already displayed in the slide show? Something like caring about number of items to display and not repating before the rest are displayed what ever the order...

This is what I would expect from random sort order: take my X items, mixed them (create a random order), make a slideshow with them, when all are displayed, mix again a create a new order for the next loop of the slideshow.

Thanks!
