I will try turning off "auto import" but please be aware, it has been on for years with no problem, and I have not suddenly imported a large number of files. They are ripped in small batches when newly added and imported at that time.
The files are all compatible PCM, Lossless, or High Rez. They are stored on a local internal drive connected via sata.
My question on the windows problem is this? If it is a windows problem, it is not happening with any other program at all. Only MC. Perhaps, and again I am no expert, but just maybe MC has a bug making it non compatible? It seems to be a recent problem here on the forum for others as well?
OK.... going to try update now
