Seems like not a lot of people use white or black screens.... we have a 30% gray that we use...
A lot of people took it upon themselves to change it, which other people would change again, then others change again, and on and on and on.... so I added a few lines of code that set the background color when a file is opened, and again when it is saved.
It sounds a bit strict, but sets everyone on the same page, and updates older files to the current standard. Since we already have an office-custom add-on that uses Event Detection (usually for setting text and dimension defaults), it was pretty easy to add.
