Testcase:

default-window:min-width-chars = 10.
default-window:min-height-chars = 10.

 def var h as handle.

create window h.
h:title = "second window".
h:min-width-chars = 10.
h:min-height-chars = 10.

def var i as int.
def var ch as char.

def button btn label "a button".

form i  skip ch skip btn with frame f1 side-labels title "the title".

i = 12345.
ch = "abcdef".
display i bgcolor 3 fgcolor 4
        ch bgcolor 4 fgcolor 3
         with frame f2 side-labels title "second frame" in window h.

UPDATE i ch btn with frame f1. 

When you click on the second window, the focus is immediately returned to the first window.

Backward focus switching is triggered by ThinClient:10963:

// in case a GO event was generated by this key, then no
// focus adjustment is needed
if (isGoPending == 0 && canAdjustFocus && fixFocus)
{
   focusManager.adjustFocus();     // <<<<<<<<<<<<<<<< THIS CALL
   // if no focus, then frame as target must not be used
   frameAsTarget = UiUtils.getCurrentFocus() != null;
}
