This app is awesome, but a major problem

Im a budding artist, and Ive only had a few months of experience, and this app is great for a beginning artist just starting out. But lately Ive experienced a glitch where the flood fill tool fills in the whole canvas, and I have no gaps in the line art. I dont use this app as much now because of this problem. I may have to resort to another app because of this. Please fix this in the next update :)
