I have an issue where a checkbox column in a TAdvStringGrid does not display correctly when navigating to it using the enter key when its parent formstyle is fsMDIForm. When navigating to the cell containing the checkbox, there is no visual indication that the cells is focused, and the checkbox does not display as checked or unchecked when pressing the space bar. When navigating away from the cell using tab or enter, then the checkbox does then appear correctly (ie, it is ticked if I had pressed space whilst in the cell). I've attached a project which demonstrates the issue. A label on the form explains the steps to reproduce.
