Good point about the EULA, I was poised to ask DxO for a copy as it only gets downloaded if Lightroom is installed on the target machine. However, I have just started trialing version 5 and discovered that DxO have changed how version 5 works with image files that are sent to it using Mac OS “Open With” command. It places the images in either the selected project or creates a new project if none is selected. Sometimes the images are placed in two new projects which I guess is a time of arrival issue : I say this because I had similar issues with my own app. Either way its a great improvement and means it is a lot simpler to edit images in Photolab that have been selected in the Finder or some other file management tool.
I shall be upgrading for this feature alone.
