Hi Martin, that's just how the size box is designed to work - your typed in value is only committed if you push Enter or Tab on the keyboard, not if you just click somewhere else.

That's the same behavior generally throughout the entire MoI UI... For example if you start drawing a rectangle and type in 10 to set a width of 10 but then click somewhere else like on the "Rounded corners" checkbox without actually pushing enter, your typed in value will not be commited. Typed in values are commited throughout the UI when you push Enter or Tab to signal to MoI that you're finished typing in that field.
