I'm sorry about it happens. I didn't recognized it because I tested paid version primarily.
This is one of replies about WikiMind lite and it says that ad is too much. I understand this complaint.
The screen shot above is captured from the GingerBread emulator. Though it must better than that screen shot in your device, but it must fix very soon. I'll remove the ad in editor screen.
Now I'm working on other user's request that enters editor screen when create new document. I'll release this fix with this new function.
Again, I'm very sorry about it.
