Has anyone had any difficulty calibrating the front sensors? I have tried multiple times and all have failed when using my regular desktop computer. I took my Phantom 4 to work and calibrated it on the first attempt so I'm wondering if it has something to do with my computer monitors or perhaps difference in room lighting. There is a slight difference in resolution of my monitor at home versus work (1600X1200 vs. 1680x1050). I event tried it on my laptop and it calibrated first time without issue. But every time on my desktop, I get a failure. It's interesting to note that as the calibration percentage progress is displayed at 50% it pauses longer on the successful calibrations. When it fails, it hits 50%, then a split second later it jumps to 100% and indicates failure. The Assistant is version 01.00.0002 and the Phantom4 firmware is 01.01.0301. I believe that is the latest on both. All sensors are clean with no smears or smudges and the monitor is about 21" diagonal (with a 4:3 ratio).The calibration process progresses without any errors or exceptions.
