Query: exploding pyrex!

yup this did happen to me tonight! i've had this dish for months and ive even put it under the broiler! but today i guess it was really cold out. i read online that the dish can explode from thermal shock! i emailed pyrex to let them know. but i doubt they will do anything. i think the new pyrex dishes are made differently than the vintage ones! i love the old ones!
