For some reason, on a new project, when I save with different tracks opened in the track pane it invariably opens after closing with only one (True Piano).
My screenset hasn't been saving correctly either (opens meter/key window and console even after I unlocked the screenset closed them and then locked again).
Any thoughts on what could be amiss my friends?

Sorry mate, not a clue.

You've done the obvious thing - unlocking screenset, making changes & saving again. This normally cures it for me.

I uninstalled/reinstalled x2a yesterday and it still did the same thing...but after this stumping even Bristol I had to go have another look...I renamed the screenset and now it's working as expected...I haven't a clue as to why it wouldn't save the 10 times plus before except something to do with changing the name or uninstall/reinstall.
All seems well now though...thanks buddy

No problem mate, even though I was of zero use

Sometimes doing the simple things works.

I had a problem with a screenset the other day - every time I tried to load it, it would crash Sonar.

In the end I duplicated one which did work to the one causing problems, and all was back to normal.

Bloody computers.......

On the contrary bud, after your post I realized it's probably not simply user error as usual...which led to me thinking the file might be corrupt which led me to renaming it which made it work again.
So even though you didn't suggest I rename it because it may be corrupt you led me to do so and now it works swimmingly!
