My problem may be the same as a lot of others that I've seen reported but here is my version. After booting I move the cursor to the 'Start' button and the hour glass appears. After several clicks I get the message "Windows Explorer is not responding" followed by another message about problem determination. I then get a message about restarting Windows Explorer. I restart it and all is well. The only activity that I could identify was Avast had just finished updating. This problem is very intermittent. This is a clean install of W7 Pro 64 with all current maintenance. Hardware is a Thinkpad T500 with all the relevant Lenovo specific drivers. I am the only active user on the machine. This system has been running since early January. The problem started about 2 weeks ago and has occurred 4 or 5 times. I boot every day and most days there are multiple boots. No changes (that I'm aware of) to the configuration. Anyone got any ideas or opinions. TIA for your help.
