My experience with warping cursors comes not from X, but from the Apollo DM, which routinely moves the cursor out from under your hand. I think it's "immoral" to warp the cursor for the simple reason that the new cursor position will no longer correspond to the position of the user's hand. Example: I move the cursor to the upper left to select an icon to de-iconify. When I do it, the DM warps the cursor to the bottom line of the window thus created, moving it more than 3/4 of the way across the screen. Now my hand is in the upper left of my mouse pad and the cursor is much nearer to the lower right. I find this very annoying. I also dislike warping cursors for a more philosophical reason. I do not like machines (or programs) that presume to know what I, the human, am up to. Going back to the Apollo DM example, I often keep a number of manual pages in iconified windows at the top of the screen. Sometimes, I like to open up a number of them for examination. Without the warping cursor, I could simply select and de-iconify each one in turn. Because the DM warps the cursor to the bottom line of every window as it is opened, I have to lift the mouse, reposition it, and drag all the way back for each icon that I want to de-iconify. The window manager should just let me move the cursor as I see fit. I've never met a warp that I liked. Perhaps I haven't met any of the really good ones. Elias Israel | "Justice, n.
