HELP!! I downloaded the free trial and it looks AWESOME! Especially with the tilting on the MacBook, I'd say it's a buy for me. HOWEVER, when I initiate the tilting and reverse the way it tilts (I reversed it in order for the water-level to remain level across the screen, other wise it made no sense), the water level became uneven. The water level was elevated at the bottom right of my screen, making it uneven. I'd just like to know, is that a bug in the free trial, the full program itself, or a defect in the MacBook's SMS (Sudden motion Sensor)? I'd appreciate an answer to my question ASAP before I go ahead and buy the full version. Thanks!
