OSX Full-Screen Cursor Jumping

[Kimball]

OS: Mac OSX 10.6.5
HW: MacBook Pro (15-inch, Mid 2009)
    2.8 GHz
    4 GB RAM
    NVIDIA GeForce 9400M & 9600M GT
    64-bit kernel enabled
GV: Alpha 2 Custom Build (r8686)

This issue may be limited to certain OSX software or certain Apple hardware. It only occurs in fullscreen mode, and has only been found to occur on 10.6.5, 15" MacBook Pro.

When units are selected and the player hovers over a resource with the cursor (tree, farm, stone etc.), the cursor will jump away from the resource (sometimes to the civic center, sometimes to another unit - I'm not sure what variables determine where it goes), preventing the player from tasking a unit on a resource. Building structures poses no problems. This issue is non-existent in window mode.

Note that when no units are selected, the cursor has no problems hovering over resources.

This is probably a problem with using SDL_SetCursor to hide the cursor (in source/lib/res/graphics/cursor.cpp). Maybe we should use SDL_ShowCursor instead.
