This is obviously something that the user doesn't need to see very often, but something that management or sales might have strong opinions about.
In a desktop application the user is probably going to go to once or twice (maybe to check version number or licence information), is it a good idea to integrate this button into the logo (since it is difficult to tell whether it is a place to click)? I have seen increasing use of this in the modern software applications, so I am wondering if it is a common practice and what the rationale is compared to just creating a distinct help or about button.
