Test(exe+src)

When “UseTakeFocus=N”, there is a problem when launching an application with
more than one window. The windows blink violently and change focus violently.
KDE becomes completely inoperable.
Please use Ctrl+Alt+F2 to switch to the console and pkill.

Attached test case(FlickWndDlgVer1/Release/FlickWndDlgVer1.exe): low
reproducibility, about 50%. If it does not reproduce, exit and try again. In
most cases, this exe becomes operational in about 5 seconds.
AzPainter2(https://forest.watch.impress.co.jp/library/software/azpainter/):
reproduces almost 99%. KDE becomes inoperable. It remains inoperable for more
than 1 minute.

Setting “UseTakeFocus=Y” solves this problem.
