Trajtracker unsupported operand type
I tried using Trajtracker in Win 8 64 bit and Expyriment 0.9.0. When the pointer click (not yet moving) on rectangle white box always causes an error :
TypeError:unsupported operand type for : 'float' and 'Nonetype'
I think the problem with the operation " - " after the different type float and nonetype. But how I solve this?
