I noticed this in Excel, now in OpenOffice.org calc. One small change in mouse wheel leads to 3 rows (line) change. Is it possible to change in Calc OR/AND in Excel?
EDIT: Yes, I know about system wide setting about the number of lines for one notch of scroll. But in some applications this setting is interpreted related to size in pixels so scrolling is predictable, but for some like spreadsheet is not. Since the height of line in a cell differ depending of the cell content, with other setting as 1 you will have a guarantee of unpredictable content before your eyes with only one notch.
