I have searched the forums and seen that others have had this problem too but nobody seems to have a resolution.
I load files into Jaikoz, then auto correct, then save using the floppy disk icon on the top menu afterwards any file that has been changed appears twice in itunes??
I have tried unchecking the itunes looking after music folder box in itunes and unchecking the auto update itunes in Jaikoz box and combinations of both these. I have cleared the itunes library and rebuilt it but get the same issue.
I sometimes use a third party programme to update my itunes folder and this has been doubling up on tracks also. So this points me to an issue with itunes itself, any ideas anyone?
