Think you can do better??? Moving a Borderless Window

[Kernelpanic]

This is a mix of WIN32 API and QB64 code. I would have posted it all in Win API, but I haven't looked into controlling the mouse cursor, only locating it. So what it does is produce a borderless window with a fake blank top strip you can drag around the screen. The limits placed on the cursor, to keep it from racing away from the window, are a bit choppy. Maybe that could be improved with a different approach. If anyone has a pure Win API example to compare it to, that would be nice.

@Pete - skillfully again from programming, but where's the practical use? 

Can precision play a role with integer numbers?  That's only interesting for floating point numbers, isn't it?
