I used to have a command.com clone that allowed easey copping and scrolling. It could be run in dos and in windows. In windows it would copy to the clipboard and have a gray background. In DOS it would copy to it's own clipboard like program and look like a normal dose screen with some extras. Had mouse scrolling in and out of windows, in dose worked best useing the arrow keys to scroll with. I remember it was one .com file. I wish i could find it again. I not eaven remember it's name. Can any one help me find this shell, workes better then the windows one thats why I'd like to have it.
