I just bought one of these guys to replace my old 3.0 but I have a slight problem. I'm a big Warcraft player, and I like to have the Alt button bound to the large thumb button (normally assigned to "back" in a browser). This was no problem with the 3.0 and IntelliPoint 4.1 software (which I have). However, the new IntelliPoint which recognizes the 4.0 doesn't allow you to bind the Alt key for some stupid reason, and the old software won't bind keys to the 4.0, even if I try to tell it it's an older version of the mouse. Anyone have any idea (outside utility, registry edit, etc.) how I might be able to work around Microsoft's desire to release updated software with less functionality?
