Editing groups and mouse messages

[Mark Schonewille]

Hi Richard,

Why edit the group? Can't you just get all layer numbers of all  
groups, take the highest number and set the layer of the target group  
to to that number? Subsequently, get all layer numbers of of the  
controls in a group and set the layer number of the target control to  
the highest number. This should help, in case editing a group indeed  
messes up messages.
