Change or set size/dimensions, not scale..!

This isn’t even an AS2 question-- it’s about the IDE. How can I set a mc’s _width and _height properties without affecting its scale?

I drew a rectangle, and to fit it to the proper dimensions, I set its width/height in the properties pane, but lo and behold, Scale got jacked. This has got to be a simple operation, but I’m not seeing it…

thanks!
