Not sure if this is an Apple issue or Adobe but my INDD icons are no longer showing in Finder in column view, instead I get a blank white icon. The strange thing is that it shows preview window and the small icon shows when I Command+I view. I have older saved INDD files that do show the icon so I think its newer saved files.
Note: I just did a clean install of Yosemite 10.10.2 on my SSD and have an internal TB drive that serves files only. The attached image is a new file on the TB drive, separate from my system SSD.
