I have problems with tagging and renaming (moving) files from properties after which a tagging error pop-up appears and asks to make sure that the files are not read only, not in use by another program etc. (which they are not). The strange thing is that this only works from time to time, i.e. at times I repeat this excercise several times with several files and the tagging error keeps on popping up and then sometimes I try the same files again minutes later and it works. I never had this problem with previous versions of MC, however I am wondering if this could be a network related issue as I have MC12 installed on 2 different PCs but the problem consists on either of the PCs with the library files being stored on only one of the two PCs. And of course I have made sure that all my directories and file name rules are all setup correct. Any ideas?
