InDesign (Mac) won't open files - creates lock file and says file already open
Hi. I have just upgraded InDesign to v15 via Creative Cloud and this issue has started every time I try to open a stored file from my NAS server. I have used the same iMac/NAS setup for years and never had this issue. Whenever I try to open a file from within InDesign it I get the can't open/no permission/already in use message and in Browser you can see a new lock file has been created even though the file never opened. If I delete the lock file and try again, same thing. But if I open the INDD doc from Browser it opens as normal.
Anyone else finding this? Any suggestions would be much appreciated!
