Working with X3 i AM BEING DRIVEN insane by the damn "Audio Dropout" popup in the right lower corner.  

1.  I already know the audio has dropped out.
2.  I am almost always going to adjust the zoom at this point and the popup is exactly in the way.  Every time.
 
I don't care that I have had an audio dropout and don't need this notification.
 
Is there a .ini or registry setting that will disable it?
 
If not I will make an autohotkey that does it, but I'd rather not.

As an alternate solution, you could use the CTRL+Arrow keys to zoom? Not what you asked but may lessen your headache a little.

I don't know of a way to suppress TOAST messages but maybe adjusting the DropoutMsec in AUD.ini might reduce the occurrence of dropouts.

Thanks for this idea.  However I have indeed tried this trick. ;)  But I am not really up for changing my workflow.
 
Also the damn popup makes me mad even if I don't have to zoom.
 
I really just hope to discover there is a way to keep the popup from happening.  I seem to remember "do not show this again" could be clicked in a previous version.
