I have a rather odd recurring problem with Windows 7 (I have the 64-bit version of Home Premium). Sometimes when I click a program icon down on the taskbar the icon will highlight for a moment and then go back to normal. The program will either not open at all or it will open about several minutes later. I have ZoneAlarm Pro, but all of my programs have been allowed by ZoneAlarm, so I know it isn't that. I have scanned thoroughly for viruses and malware and have found nothing. All my other components (RAM, HDs, etc.) are operating efficiently. I was just wondering if anyone else was having this weird issue and if so has anyone figured out what causes it? Thanks.
