Hello
This problem has been reported already. We're looking into correcting this for future releases of Measurement Studio. At this point though, the only way to get around this problem is to make sure you know where the hot spot is before the graph is inverted and use that area, as click and drag will still be valid at that point.
Sorry about the inconvienice this is causing you, but we hope to get this problem fixed ASAP.
