When there is no caret visible when editing a cell in the grid, this is because the font size is too high in relationship to the height of the cell. This is a behavior that is actually something in Windows and not specific to our component. When in a Windows multiline edit control, the font size in relationship to the editor height is too large, it won't display the caret. This can be easily simulated by dropping a TMemo on the form and decrease its height. At some point the caret will disappear. To avoid this, either decrease the font size or keep increase the row height.
