Hello everyone! I love Sonar and making music! . The issue I got is sometimes when I come back to Sonar pro after alt-tabbing away from something. I come back to having all my tracks expanded but with their height shortened. I only have 16 - 20 tracks but having to collapse them all after resizing with shift is getting old and tedious to say the least. Is there a short cut key to expand / collapse all tracks? shift+A , just selects every track for me. 
 
Cheers! 
 
 

Check out the Auto-Zoom function.

Did you press SHIFT+Z by mistake ?
This engages Auto zoom for tracks headers

I guess I will go ahead and stick with the auto zoom. Still not sure why the tracks intermittently open themselves after being closed. Auto Zoom works good enough though. Thanks Guys! 

I would like to know if there is a solution to this nag.
Every project (from SHS 6 or MC 2003 or Pro 24) that I open in X3 has all of the tracks expanded.

I believe if you select all tracks, then hold CNTRL and collapse 1 track, the others should follow.
 

If you select all tracks, hold down SHIFT, adjust one track, the others will follow.
If you hold down Ctrl, then tap your up or down arrows, all tracks will expand and collapse with the tapping of the arrows.

with Shift the others will follow exept the "active" one.....
 
The same on your Sonar? I've never recognized this behaviour....

My fault, with Autozoom activated the"active" one stays as it is
 
In Normal Mode you can mark your wanted Tracks and press "Shift F" and all of them expand to the whole screen.
 
Try also F and Ctrl-F

In my examples, you are right as I was writing from the point of using the normal mode, not Auto Zoom.
