I have a user that was just upgraded to Internet Explorer 8. When they go to a bank site and open a zipped (.gz) file it opens in WinZip as it is supposed to. When she goes to extract the file WinZip errors out and says the file can't be found. If she trys it several times (number of tries changes from one time to the next) the file will finally open correctly. Not sure what is causing the problem, it worked the day before when she had IE 6.
