No, I selected individual files; I did not use Ctrl+A.
I don't see an "Options" tab. I went thru all the Settings tabs and did not see anything about Hidden or System files.
[update] I found the options tab, but both the Hidden files and the System files are already unchecked. Any other ideas?
I dropped 3 files onto Imgburn and found that the burned disk contains desktop.ini (which I did not drop). How do I stop Imgburn from writing desktop.ini?
