Hmmm... The same could happen with accept too: * Client A owns touch * Client B has a touch grab and is listening too 1. Client A accepts touch 2. TouchEnd sent to client B 3. Client B accepts touch (which means, I accept iff I become the owner) 4. TouchEnd reaches client B 5. Client B gets an error from the touch acceptance because at the time the server got the accept request, the touch has already ended for client B We probably need to think a bit more about this... -- Chase _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
