input tabs not available in tank 2016

I decreased the input tab width in Tank 2016 software to have a bigger picture of the 3D view. During decreasing process I almost took it to the edge of the window. Now I'm unable to see the input tabs. I tried many things, but still not able to see the tab. I request you to let me know on how to bring back the input tab.

Fixed the issue somehow
