I tracked an odd issue with WindowEX.

One look-up program would trash one line of the parent (main) screen. Found that while listing the help, I was overflowing the lines by using number of lines as last line instead of minus 1 (zero based lines).

I wrote a test program and discovered that anything printed on the beyond lastline+1 would print on the corresponding lastline on the main screen.

So if I had a 80x25 screen with a 72x22 WindowEx, printing at @(0,22) would display the data at @(0,22) on the main screen. Printing at @(0,23) or beyond would print on the last line @(0,21) of WindowEx (expected result for this programing mistake).

This was tested and recreated using Comet16 2013.478 and Comet32 2013.478

Test program available upon request.
