Klaus, I have not been able to recreate the problem with the ports/pins check. It may have been related to this. I was testing, building a new screen and went to view, over view. Went back to design view and I couldn't select any object except the Image I was using for a background. So I unlocked it and moved it down so i could get to some buttons I had put on the screen earlier. This is when I got the error this time. When this happens, it takes a few minutes for the program to end task from task manager.
The more I play the more I learn. This is looking very promising Klaus.
I did see where 2 more features would be very helpful too. Not asking you to work yourself to death to implement but would love to suggest.
A snap to grid where the x and y spaceing can be entered and very important IMO is the ability to have layers. Layers that have lockable positions, reveal and hide views, and the ability to be moved up and down in the tree. Each item could be moved up and down individually.
I also sent you a PM.
Thanks,
Brett
