I am trying to work with OpenVPN. It installed correctly (or so it seems) but when I click on it, nothing happens. If I click again, I get a message "OpenVPN GUI is already running." If I type a command into "run", such as "OpenVPN" or any other command, a console window opens but then closes instantly; less than a second. I can see different commands in the window but it goes too quickly to read them. I've had similar problems in the last few days: the console window just flashes for a moment and then disappears. Is there some setting in Windows 7 I need to change?
