Glitch blocks some iTunes music sales

Some users of Apple Computer's iTunes for Windows say a glitch is causing the program to crash whenever they try to purchase songs.

Beginning late last week, some Apple users noticed that the Windows version of iTunes would abruptly quit just as they were in the process of purchasing music from the online store.

By Monday, more than three dozen users were complaining about the problem in Apple's online forum. An Apple representative declined to comment.

In an e-mail interview, iTunes customer Sherman Hall said he experienced the glitch on Thursday.

"The program stopped with a memory exception after downloading two songs," Hall said. "Attempts to restart the download, access my account information or any other one-click activity were also met with the same memory error."
