I'm tracking changes in a workbook, and when I hover my mouse pointer over a
cell, a small window opens up with details of the change. However, this is a
tiny window that shows only a few words, so it isn't very useful, and when I
try to move my mouse pointer to select the smaller window, it vanishes the
moment the pointer passes out of the workbook cell. How do I get this
display to persist longer, and how can I change its size?
