I noticed in Excel that when I type in a cell and the text almost becomes larger than the cell width, excel adds a blank line to the cell when wrap text is on. This is a surprise to me as the cell shouldn't be wrapping text, because it can contain the text quite well. What is the mechanism behind this and can this be prevented?
If I change the width by right clicking on the column and changing the width there, I can change it indefinitely without it reverting back to one row. If I change it by dragging it, I can also do it indefinitely. The only that helps is stand after the last te and pressing delete.

and drag down. If anything other than #VALUE! shows, there's something in that cell.
