Re: Re: mouse cursor problems

The readership of this forum includes WineX developers and Transgamers.  
As far as Transgamers are concerned, the vast majority probably find the 
technical aspects of this discussion too onerous to try to understand.
That is why I explicitly say whether a particular point is IMO correct or 
incorrect.  Are you saying in this letter that I am correct and that I 
have been correct for some time?  Are you saying that you were wrong?

Does B & W work with my patch?  There is no demo for this game so I 
cannot test it.  Gregory said it works.

According to Gregory and my testing my patch does not break any 
currently working game.  Did you find an exception?  (Aliens vs. Predator 
2 is not a working game.)  Did any Transgamers find an exception?

Getting raw unclipped relative mouse data from the X Server is IMO the 
best solution and should be the permanent status goal.  Are you sure it 
cannot be done currently?  Perhaps by grabbing the mouse driver directly, 
taking the raw data and then feeding it back to the X Server.

Is Aliens vs Predator 2 the only problem?  If my patch only adds 
functionality without taking away any functionality, there is no reason to 
exclude it from CVS.
