Steps to reproduce this issue:

  1. Open a viewport
  2. Drag the map with the right mouse button

If you keep dragging the map, you should probably see that the mouse pointer changes into an os pointer.
In my testcase, this doesn't happen at all if the mouse moves very slowly,
while if the mouse if moved very fast, this bug almost immediately occurs.

Reported version: trunk
Operating system: Mac OS X

I wasted many time on that bug. Finally it was not so hard (if i made no mistake). There are two things to take into account.

Firstly, the application receive a cursor update event when the pointer is virtually out of the window. Consequently, OTTD hide its own cursor.
Secondly, the application receive mouse entered & mouse exited events when virtually moving out of the window. I think that run this way but it doesn't matter:
- mouse exited first;
- qz_warpcursor is called when processing a mouse dragged (which virtually reposition the cursor inside the window);
- mouse entered as a consequence.

So i decided to catch those events and stop propagation to the application when dragging ie when _cursor.fix_at is true.
