We have 4 NT4 SP6 with Metaframe 1.8 and 1 Windows2000 SP2 Metaframe 1.8. For the Past two weeks some people are complaining the application is just minimized. You need to hit ALT F2 to bring up the screen. We have not made any known changes on our servers. I cannot duplicate the problem on my workstation. It seems to be any new images..however as far as I know the image is not new either.
