I have a screen of small trading charts that get obliterated by the DF title bar icons.

How can I exclude this app from displaying the title bars?

I have this issue too with very small windows. I love the title bars on most applications, but not (for example) on the Calculator.

I managed to exclude the application where I wanted to to stop this happening by going to the Compatibility tab in the settings window and adding the URL to the exe for the app in the main window. It's pretty easy to do and now works exactly as I wanted it to.
