Double animation swipes away the new form

[P5music]

In my app a mainForm calls another form.

I succeeded in creating a working back button on the new form.

After some changes now I have a strange effect.

I have code like this

Toolbar toolbar=new Toolbar();
// It's the same with Toolbar toolbar=getToolbar(); and with global toolbar true
currentForm.setToolbar(toolbar);
toolbar.setEnabled(true);
toolbar.showToolbar();

the last instruction showToolBar() produces a strange effect: 

let's say the new form is created and I can see its layout coming with a speedy animation from right to left, 

but then another speedy animation from right to left swipes the form off the screen.

On the toolbar the back command is visible but it is not responsive (also the menu button is present but not responsive).

What happened? I made some changes to the app, indeed I added the side menu to the mainForm and the secondary form, but it is the same also without it now.

Thanks in advance

hide/show toolbar were designed for running when the form is already showing. You don't need to invoke it when it isn't,
