Help jumbo track

Hello i made a mistake i double clicked on a track and now all tracks are jumbo, is there a way to fix this please? Thank you for your help

I use ntrack 9 ex

Use the Zoom in or the Display All. If you don't have the icons, click on the upper left side of the tool bar on the icon that tool tip should call “customize toolbar.”

Thank you :)

In version 9 you can also go to the left hand box (the area that marks the track but does not contain the wav file display) and drag the track display larger or smaller.
