A software slipup in Microsoft’s latest update to Office 2000 results in the application repeatedly asking some customers to register the program. The glitch apparently affects only Office 2000 users who don’t have administrative rights on their computer, a Microsoft representative said Thursday. “They are experiencing unexpected registration prompts, but it doesn’t interfere with product functionality,” he said.
