Seems I'm not alone.
I noticed this about 2 days after installing the screensaver (and app... it looks the same) and I've never seen it not do this since then, so I'm guessing it's always been that way. I've also deleted and reinstalled the app and trashed the preferences (at least the ones I could find). None of those made any difference in how the starfish looks.
I've decided that this is a feature... my starfish is just into yoga.
I've attached a series of 15 screen shots of my starfish in various deep sea yoga poses. You may notice it's very limber.
All joking aside, I'm not too worried about it... the screensaver is still gorgeous and I'm very happy with the purchase. And I'm very glad that an update is in the works to remember the starfish position.
Who knows, maybe that change will fix it... could be that being stuck in one place is what has it all stressed out and doing yoga.
