I had no problem before. Just recently, everytime I tried to print out international postage label, all my windows just closed. No error message shown. Just blank and shut down all previous windows. I use IE, but the same problem when I change to firefox. I have to cancel label and request refund. Then go to post office every time. I hate to do that. Anyone please help me to solve this problem. My OS is window XP. Thank you.
