I can replicate this but not reliably.

Sometimes switching between fonts and then changing column width causes a
column width setting of 15 to change to 14.86 but the strange part is not
always. It happened most often switching between Calibri and Arial font.

,I am an instructor teaching Excel 2007. There is an assignment where my
students have to change the width of several columns. They would like a
column width of 15.00. If they use the mouse to change the width, they can
get either 14.75, 14.88 or 15.13. If they right click on the column and click
Column Width then enter 15 or 15.00 and click ok, they still get 15.13 when
checking with the mouse. As I'm grading these assignments I have attempted to
change the widths and find I'm not able to get 15.00 either. Can anyone help
me?
