When I attempt to open a command-line style program, the window opens for a fraction of a second during which i can see some output but then immediately closes. This happens no matter how i have the program configured to run. I am the admin. No compatibility modes work, no security settings, running as admin, nothing works. It happens for all command-line style interface programs. For example, kill.exe, tlist.exe, etc. I have scanned for viruses using avast home edition. I have a 64 bit windows vista computer running 4 gigs of ram and a centrino processor. Any help would be appreciated greatly.
