I have found that with a check control that has associated text, when the check box is ticked or unticked, a dotted outline around the text is displayed.

Similary if there is no text (the text being handled separately from the check control) is ticked/unticked a small 1 character high and wide dotted outline appears where any text for that check control would have been (to the right of the control).

Is this something I have done that causes this to happen, or is it something that I just have to live with ?
