Thank you. I did see it as positive, for your remarks were usefull. I looked already for bigger buttons without spaces and it becomes better. I thought already to make one button too switch between buttongroups in that way you can use 3 or even more groups with buttons for several departmens so you get 3x40 or even 5X40 buttons. And by the way colors is very easy to realize to make it more clearer. I certainly will use your remarks.
