I am unable to draw a mask rectabgle larger than the composition viewing area because it does not scroll whe I get to the edge. It should scroll.
How can I select a larger area? I try to resize by dragging the corber but it does not drag it evenly.
Just reduce the view magnfication ratio in the Comp panel to 50 per cent, 25 per cent or whatever is required to have enough space to do this?

Hold down Ctrl (centered) and Shift (proportional) after you have double-cliccked the mask to invoke the transform bounding box. The rest is not really clear, but as suggested, simply zoom out. Masks are layer-relative, so they are not bound to any fixed sizes, not the layer's, nor the comp's.
