Arranging Views
The ‘View’ toolbar 
and the corresponding menu offer the usual functions for arranging views – cascaded, and horizontally or vertically tiled. In addition, the software offers with the 
button, the option of presenting the views in tabbed form. After the 
button has been activated it is locked to prevent access to the other functions for arranging views. By clicking once more on the tab option button the views are once again cascaded.
