I booted up my computer today and found that instead of the "coughdrop" visual style my computer was using the "windows classic" theme. I went into style xp to see if the theme changed but it did not. It still said I was using the "coughdrop" visual theme. So, I told it to switch to default XP, then I switched back to "coughdrop" and everything was back to normal. What could have caused this? Is my computer messed up?
