I guess I really wanted to know why this happens. Is there something I can do to prevent it. I have been saving files for 3 years and this has happened one other time to several of my EQ5 files that all had similar names. It locked them all up. That was last year and now it's done it again. There were two files a version 1 file and a version 2 file and it locked them both up suggesting it wasn't an error when I saved the file.
Same with the EQ it was all files that had the Half Square words in the title of the files. It wasn't just one file. So I am curious what triggered this.
