monitor blank area of window for any change

[AggieBQ1972]

Here is my macro:

RECT r
SetRect &r 1170 260 2160 510
int w=win("WSJT-X   v2.0.0   by K1JT" "Qt5QWindowIcon")
wait 0 -S "" w r 16

#region Recorded 1/19/19 4:50:02 PM
int w1=act(win("WSJT-X   v2.0.0   by K1JT" "Qt5QWindowIcon"))
lef 1139 26 w1 ;;title bar
lef 1044 992 w1 1 ;;push button 'Erase Alt+E'
lef 1748 990 w1 1 ;;push button 'Halt Tx Alt+H'
#endregion

I am attaching screenshot.  QM Floating toolbar is located just below the coordinate 1170  260.  When run, I expect that when the lines populate in the right window below  1170 260 that QM will run the recorded portion of Erasing the entire Right window followed by Halt button.  As you can see from the attached image there are multiple lines populating even below the QM toolbar which according to the 4 coordinates should be in the area watching for changes.  Can you see what might be the problem?  Thank you veery much!
