I am an iPhone 4 user and I just downloaded the latest update that included the nitro and wind improvement and as soon as I opened the app it was flashing muti colored lights over 3/4 of the screen the 1/4 that wasnt flashing was my area to draw. I cant use this app at all because of the flashing screen and one inch by one inch drawing area. I restarted my phone tried the zoom/option changed the setting and nothing please fix this as soon as you can thankyou
