    The implementation of XtGrabButton in X11R4 (at least, in the one we have
    here at CSRD-UIUC) does not agree with the description in the Intrinsics
    manual.  Specifically, the calling sequence is given in the manual as

The spec is correct and the implementation is off. Checking the interfaces for 
spec conformance fell between the cracks when this code was added during late
beta. The bug was made obvious to us when we ported the motif library to R4 
(via a protocol error :-). 

It has been reported to MIT and will hopefully make it 
into the public patches at some point. If you are not using synchrounous
grabs and/or the Xt focus mechanism then you shouldn't be impacted by not using 
the Xt wrappers for the X grab interfaces.
