weird blue outline on selection buttons
My problem is a bit difficult to explain, so I have included a few images below to aid in my explanation. Recently, when I have, for example, the option of saving, not saving, or cancelling the action in a program, the dialog box pops up and one of the selection buttons is blue (like normal) but the other two are outlined in blue. The same thing happens when I open iChat- the drop down menu where i can change my online status is outlined in blue.
It is not a serious problem- more a matter of aesthetics, but any explanation of how to make the blue outlines go away is much appreciated. Thank you.
