Hi!
On high resolution retina displays (2880x1800) actipro windows get a 6px wide black border around them. Also the 1px light border around the window looks a bit ugly in the top/top-left corner.
See attached screenshot:

Also checked if visual studio has this problem, but visual studio looks good:

Not a critical bug, but wanted to let you know.
Thanks!
