HI James, I was not aware of this difference in behavior and don't recall a change that specifically might change this, there were a number of internal changes though, perhaps one of this introduced the different behaviour. When you say you see the same behaviour with the osgkeyboardmouse example could you explain more specifically what to look for in this example, do you have to modify the sources? If so could you provide the changes.
Thanks, Robert.
