I have never used the stock sense six firmware but I have noticed that on this Rom, if you tap on the screen just above the HTC logo, it acts as if you pressed a hardware menu button (the menu for the app you are on pops up).
This feature is interesting, but the problem is that when I type and push the spacebar ever so slightly too low on the screen, the keyboard closes and the menu pops up. This has finally become annoying enough for me to make this post and I hope someone can help me disable this feature. Thanks!
Also if anyone knows of a relitively stock sense six Rom without this thing, please let me know.
