Regarding Frontlines 1.00 (UT3 mod), mouse isn't working at all ingame
I found out, that the mouse is handled like this:

mouse_init();

...

while(1){

dinput:IDirectInputDevice2WImpl_SetCooperativeLevel( DISCL_FOREGROUND|
DISCL_NONEXCLUSIVE )

input:SysMouseWImpl_Acquire <- queue is cleaned here !

dinput:IDirectInputDevice2WImpl_GetDeviceData  <- queue is empty, return
nothing

dinput:LL_hook_proc calling  <- mouse hook, fills the queue
dinput:dinput_mouse_hook 
dinput:queue_event 

dinput:SysMouseWImpl_Unacquire 

}

The basic problem is, that SysMouseWImpl_Acquire() clears the queue AND the
mouse hook is processed after IDirectInputDevice2WImpl_GetDeviceData() every
time.

In dinput/device.c : 
HRESULT WINAPI IDirectInputDevice2WImpl_Acquire(LPDIRECTINPUTDEVICE8W iface)
uncommenting this lines fixes the problem, the game is working fine

 //This->queue_head = This->queue_tail = This->overflow = 0;

better solution would be getting the mouse hook processed AFTER
SysMouseWImpl_Acquire() and BEFORE IDirectInputDevice2WImpl_GetDeviceData() is
called.
