Tracks won't stay hidden...

Possibly this  You've just hit this by mistake. SHIFT H 

 
And You do need to save a LENS if you have a layout you always use. 
Set up your screens the way you want them and then save that. I use the Advanced for mine. 
 

You could move all hidden tracks to a new track folder, that way if you do accidently unhide them you've only got the track folder to unhide again.

This has been reported a few times before and it's happened to me on many occasions. I really don't think I've accidentally hit shift-H - I've seen it happen when I've loaded up a project specifically to tidy it up, have hidden a bunch of tracks, hit save and then opened it the next morning to find all the tracks unhidden. I've also had archived & hidden  & archived MIDI tracks completely disappear from the track manager, never to be seen again. It was buggy for sure. 

nope...this is all audio...this is in the voiceover suite.  I think I'm on the latest version of SPLAT.  I tried the above track solution...but no love.  It's pretty maddening because I've got about 8 or 9 raw vo tracks that I've pulled clips from to build 4 spots with FX and music and they clutter up the screen making hard to see which is the master vo track.  Sucks.
 
Plus...rant on...Why oh why did they change "clone track" to "duplicate track" and, worse, make its default state to NOT duplicate the "events".  That is just crazy.  If it ain't broke...they'll break it.
 

I wish I could do that ol pal!  But, unfortunately, it don't pay the bills...although I wish to heck it would:-)
 

Im way too lazy a sumb**ch to have to search for somethin I already been doing for twenty years.  My point is that...I don't believe there was a caterwhaulin outcry that the "clone track" feature just had to be changed or 90% of Sonar users were gonna revolt.  Or did I miss somethin while I was asleep?

I’m simply failing to understand how this makes things more difficult.
It doesn’t, in fact it makes things easier.
Your wish is granted sonar is now in a vacuum and will no longer be updated.
My point was that sometimes a quick google search is faster than waiting for someone to spoon feed you answers here.

Sometimes it’s not what 90% of users want it’s about making a better product and as combersome as an “Clone track” button might seem, nothing changed except now it’s easier to clone a track/multiple tracks

But don’t let me preventing you from complaining.

I really would love to know what causes this problem with hidden tracks unhiding themselves. It's weird because it seems to affect multiple projects simultaneously. I have a 150+ track project with about 50 tracks hidden and every now and then Sonar will unhide all of those tracks - it takes me ages to hide them all again because I have to go through the whole project and make the "hidden/not hidden" decision for every track. 
 
It hasn't happened in a few weeks but last night it happened (grrr), then right after I'd finished re-hiding everything I opened another project in which this has never happened, and all of the hidden tracks in that project were unhidden too. Makes me wonder if it's a bug which happens on a global scale and not "per project." Between stuff like this and having to reload presets for all of my EQ's 3 or 4 times during a session, it's a wonder I'm making any progress at all.
