Thanks for the replies AZ and Matt.
AZ, I disabled it in the startup options, and it doesn't load when Sonar initially runs, but I don't know if you mean it can be disabled "globally".
Matt, following the disable process as a startup feature, it still comes up when I press the F1 button. It is a little frustrating as the F1 button was a great "1 click" way of saving often while working on a project. That function seems to have been lost with the introduction of the Start Screen. I actually think the Start Screen is a good feature, I just don't want it to pop up when trying to do a save.
You mention that your FW-1884 is sitting idle due to lack of driver support. What do you mean by that? Apart from the issue I have raised I seem to be having a good time with it with Sonar Plt and Windows 7. It also runs under Windows 10 for me for "general audio" without doing anything special beyond the original automatic web upgrade (I am not suing Sonar under Windows 10 though).
