When I have a fixed with columns in a table, the number of lines required to display the content of a cell on the screen can deviate strongly from the number of lines in the .dvi output. When the zoom percentage in the edit -> preferences -> look & feel -> screen fonts, is relatively low, the number of lines required to display the cell contents can be much larger than on paper. This is caused by the fact that the cell internal margin is not scaled with the zoom factor. Not a really important bug, but under certain circumstances an annoying one.
