In Overview, data older than 1 months is bad. Is this a bug in the new SleepyHead version? Or is it SleepyHead on my Windows 8 computer? Anyone else have this problem? AHI older than 1 month is too low, roughly half the correct value. Correct values can be seen in my backup of previous saved RedMed data. Correct values are also available in my notes for those days. Same problem on the 2 previous versions that are available for download. I had this problem in 2013, but it went away with the late 2013...
