Little XOJO 2017 rel2.0 OPEN NEW TAB IDE concern

XOJO rel 2 put me back to the main tab after clicking an object from newly open tab.

Anybody experiencing it?

Was the first tab locked?

yes, the new tab was locked.

When clicking some object, it push me to the main tab. Is it the default behavior?

I meant… was the main tab locked.

the main tab is not locked.

And even I locked the main tab, the scenario still the same. Then send tab move me to the main tab when ever I clicked some object from 2nd tab.

However, I tried to experiment some other way and it is now function ok.
First, I made the main tab LOCKED, then the 2nd tab is not locked. It works fine now.
