Software doesn't change its behavior suddenly; _something_ changed on your
system which caused this behavior. Did you upgrade any core libraries?
Apply any patches?

She walks in beauty, like the night
Of cloudless climes and starry skies;
And all that's best of dark and bright
Meet in her aspect and her eyes;
Thus mellow'd to that tender light
Which heaven to gaudy day denies.

-Lord Byron
