Before Excel 2007, in older versions, you could see the row height or column
width change before your eyes with an screen tip indicator while you
positioned the mouse pointer on the line between the rows or columns then
clicking and dragging to increase or decrease height/width. As you drag the
line the number of pixels & units was displayed in a screen tip.

Now it seems Excel 2007 doesn't do that. Or is there a way to enable this?
If not, why would they disable a valuable time-saving function?
