I'm trying to greatly increase the line weight around a box in Excel
2007. If I go to Format/Format Cells/Border I choose the darkest line
for the box, but it is still very light. I want something really
bold, like 1/16" line width.

I looked in the Help and it refers to, under Drawing Tools, on the
Format tab, in the Shape Styles group, click the arrow next to Shape
Outline. I can't find any of these things. This new format for Excel
drives me crazy.
