Just tried the app again today after I updated it on the Market. I'm getting the same results though.
I didn't post after my last experiences with it. So here is the deal with the latest update, and before the update. All gestures are working for me. The only one I have issues with is the Status Bar. It does hide and show when I ask it to, but with bugs. Everytime it reappears I get the "Preparing external storage", I which I could live with if that was it. Big problem is my wallpaper goes away when the status bar does, just solid black. When the status bar comes back, the stock Asus wallpaper with the field and tree shows up. Hide status bar again, and wallpaper goes black. Bring status bar back and Asus wallpaper comes back.
Pretty strange I thought. Hope you can figure it out. I planned on buying the app to show my support if it worked good. If you can get this straight you get my money Again, thanks for the help. Hopefully you troubleshooting mine will help you make the app more stable for future users and then future purchasers of your app. I will definitely be recommending it to my friends as well.

Summary: if you just want to hide status bar on ICS then custom Rom or Mod will be better.
