Very strange behavior in catia

[Ciccio]

Hello i have installed catia v5 r2017.
When i click on the instrument bar some instruments split and there is no way to put then in the proper place.
Is there a solution to this strange behavior?

In the top menu; Tools + Customize to display the Customize window. Then click Restore All Contents and OK. And click Restore Positions and OK. Close the window and your toolbars should be back to normal.

If this doesn't help, please attach a picture so we can see your screen.
