>I've got a grid I need to slow down due to the key-repeat rate being too high. If anyone knows the API call to set the rate, let me know...

There's no way to do it via Win32 that I know of. Like many other things in the control panel applets, this is generally something you don't want to mess with. I know if an app slowed down my keyboard without my permission, I'd be a little irked. :-)
