Until yesterday, Itunes was working OK on my PC (Windows XP). It's installed for 2 users. The only thing that wasn't working properly was the "coverflow" feature, which didn't bother me too much. I did a bit of work on my PC yesterday. I installed a new graphics card and switched from NTL to SKY broadband, and installed McAfee. Everything is working fine. However, Itunes is now causing my PC to crash. Oddly, it only does this for one particular user. It works like a charm for the other user. Any idea what might be causing this?
