After having used the command "appdesigner" at command window:When an app is running at app designer the same app is automatically running at the main window too.

After having used the command "appdesigner" at command window, the behavior of Matlab changed. Now on I can't run an application at app designer and at same time run another script at main window. Both windows run the same programm whichever starts first. When an app is strating running at app designer the same app is automatically running at the main window too and vice versa. I used Matlab 10 hours a day 3 months ago with no such behavior: I cant run an app at app designer , stop it at a breakpoint and then use the main window to run a script searching at app variables etc any more.
Thankls in advance.

Is behavior any different if you start AppDesigner from the Apps tab link instead of from the command window?
I start app designer from Apps tab. I started once from command window and hell came on earth.
??? I don't understand fully the comment???
I gather from the original question the issue from the command line start, but did the behavior change when using the Apps tab or not?
