[pygame] can't grab the input while fullscreen on macosX10.4

[Mikel Izal <mikel.izal@xxxxxxxxx>]

Hello

I have this problem using pygame (1.7.0) fullscreen on Mac OS X  
(10.4). Even if I set the cursor not visible and call get_grab(), I  
cannot efectively grab the input. The cursor remains invisible but  
looks stoped at the screen edges and relative positions are returned  
as 0s.
I have tried to grab the input directly with a C program using SDL  
and it works
I have build pygame from CVS and still it fails. Looks like the call  
to SDL_WM_GrabInput(SDL_GRAB_ON) on event.c has no effect. If I print  
the result of  DL_WM_GrabInput(SDL_GRAB_QUERY) just after that line  
it says it has not grabbed input.

Can someone please provide some help? or at least confirm that it  
works on tiger?

This is the code I use to set a fullscreen grabbed invisible cursor
------------------------------------------
pygame.init()
pygame.display.init()

print "get_grab() 1 returns "+str(pygame.event.get_grab())

pygame.display.set_mode((800,600),OPENGL | DOUBLEBUF | FULLSCREEN)
pygame.mouse.set_visible(False)
pygame.event.set_grab(True)

print "get_grab() 2 returns "+str(pygame.event.get_grab())
-------------------------------------------

Without the the FULLSCREEN option it works. The second set_grab()  
returns 1 and I can get mouse relative values forever without  
reaching the screen edge
With the FULLSCREEN option the second set_grab() returns 0 and the  
invisible cursor stops when reaches screen edge


I can reproduce it also with the program eventlist.py in the pygame  
Examples directory. Adding the flag FULLSCREEN at the set_mode call.  
On mac os 10.3 I can get the grab light green on window or  
fullscreen. On 10.4 I can only grab if not fullscreen


What more can I try?

Thanks for any help  :-)
