I'm getting blank lines at the tops of text cells. Column widths are fixed
and row heights are set to AutoFit. Cell alignment is set to Wrap text.
What am I missing?

Simple spreadsheet to track time spent on a project. First column is date,
second column is verbal description of work done, and third column indicates
hours spent on those tasks on that day. First and third columns are always
one line and set for Top vertical alignment. Second column is typically
several lines and is the one giving me problems. Changing from the default
Bottom vertical alignment to Top has no effect.

Solutions will be greatly appreciated.
