So...I'm in Mail, click slightly off-center on an icon for something and the icons on my toolbar vanish, leaving only a thin line of text. I NEED those icons! Even tho I (apparently) don't hit them dead on...I can't find a pref or way to put them back.

Then, days later--apparently I'm "off" again, because it turns the same magic switch, in true Apple fashion--and my icons reappear.

Can you help?
