this usually happens in Acrobat pro DC and Illustrator.
I will try to save a file over another file with the same name.
I will get an error message saying it cannot because the file may be 'read-only'. I check the file properties and it is not read-only.
windows 10 , 64 bit.
Disable the Preview panel in Windows Explorer.
bummer, I got excited.
but I checked and the preview panel was already disabled in explorer. (in fact I did not know that was even an option)
I will check and see if 'view' option set to 'list' instead of 'icons' will work.
any other options? Thank you so much for replying!!
