Any general steps to repro? I'm trying to repro but cannot seem to do so. (I'm using PS Touch 1.5.1 on a Google Nexus 7 (2013) with Android 4.3.)
I try to zoom in all the way (400% is the max) and cannot get it to crash.
Nothing special to repeat. I'm fine tuning existing lines(red and green). It seems to happen every time after a while. Last time zooming was around 270%. I'm running iOS7 in iPad3
