I agree, Brian , make it simple!

I agree. I got caught out by this several times, but then I started just selecting Master Bus as the export target and that works just fine providing everything you want to export is routed to the master bus.

I agree too. I don't know of any other DAW that defines your export mix by the tracks or even clips that you have selected, though pretty much all of them let you do a timeline selection. It could be argued that this is what sets Sonar apart and makes it powerful but most of the time it makes things more difficult, not easier, at least for me.

Not sure I get what this is all about, but I usually ctrl+A to select all for Export unless I KNOW nothing is focused. If there's any tracks I don't want in the mix they are Muted beforehand.
 
Just a habit from using older versions of Sonar where selecting nothing would end up exporting a blank wave file.

I do the same but you have to admit those extra steps aren't very intuitive.

I always use the "what you hear" preset in the export dialog. Does exactly what it says on the tin, except it doesn't select 64-bit for you.

I think one of my biggest frustrations is when I export a synth track and end up with an empty wav file because I didn't select the MIDI with the audio track. I mean really, what's all that about? I'm not exporting the MIDI am I?

I also find export "entire mix" confusing and always export hardware outputs.

I'm firmly in the camp of Select None and export through Main Outs.
 
It never fails.

I'm a fan of adding a "What you hear", which exports exactly the same thing you'd hear if you clicked Play on the Transport. It really can't be less confusing that way. I would just prefer CW to change Entire Mix from what it apparently means to what most of us would infer, or to add a What You Hear, option.

+1
Would be nice if there was also a timeline adjuster prefilled with the selection in the export dialog.
