Look for the Application Compatibility Toolkit (ACT) as described at: http://support.microsoft.com/kb/294895 removing it helps some computers a lot. Another program that causes problems on some computers is the MS Office 2010 Click-to-Run system. It's usually associated with the trial version. With this system, software is downloaded and installed dynamically as it is used. Hangs and slowdowns when logging off or rebooting were noted. Removing this will help. If MSO is needed, the DVD version can be installed. Also removing .NET and re-installing it can help some computers. -- Regards, Mike -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
