milkshape is being a bitch and when I try to use the scale tool on a shape and i barely move the mouse it compacts it into a flat sheet and when i move it again it does it again and turns it into just a dot.
Are you just clicking and dragging on the viewports? Maybe you're zoomed out too much, the zoom really affects the scaling, zoomed out = fast scaling, zoomed in = slow, but more precise scaling
Which i think is kinda dumb, but it's actually helped me in some situations, so whatever
