472kHz WSPR this evening

Several reports of my 5mW ERP this evening, but I am suspicious that I am not reporting stations I am copying to WSPRnet! Have I forgotten to tick a box (again) or is this a bug? I am sure I ticked the upload spots button (checked - it was ticked). I shall close and reopen the V1.6.0 program. According to my local screen, I spotted no stations at all. This is most unusual, so I have restarted the program and resynced time. We will soon see if I spot others now!
