Draging components from off the window does not work

I have imported the project from 7.1.8

At some time in the past I shrank the window. Today I noticed that a component (not visable) was off the window. I tried to move it onto the window with limited success. Arrow keys didn’t work. click and drag didn’t budge it.

The only way I got it on the window was to grab a sizing arrow and resize it. (thus destroying it’s appearance)

Try holding ALT and dragging it.
