With the latest Beta I’m getting frequent Java errors during registration. I’m using APP to calibrate and correct my comet frames, use PI to do a comet-alignment and then integrate again using APP. Same for the frames I corrected in PI (stars only, substracting the comet) and then integrating in APP. Here’s a screenshot, the error pops up just after the memory to file mapper closed message. I clicked the error away and no integration was done.
