It may be made that way for a reason, but most other things in Wine, as well as most well made programs, have a lot of options, without certain things forced on you... so it seems strange theres no way to disable it. I don't care if something tries to load a web page and it shows a blank white screen, or errors or even crashes. I make a certain prefix customized for 1 specific app, and if that 1 app doesn't need it, ever, for any reason... why install it? Its not so bad when it asked when it actually tried to use it, but now that it asks every single time your prefix gets updated or created, it turned annoying.
