FEST unable to click on menus under windows 10

[zenddup]

Hi,
when I run test testcase under windows 10, it cann't click on the main menus,but on the title bar.
It works well on windows 7.
Under windows 10, the mouse alway click on the title bar,the showed a pop-up menu is like[Maximize、Minimize ...]
How to make it click on the right menu bar on windows 10?
Thanks,
Johhny.

Some problem occurs in Ubuntu 19.10 with gnome 3.34, it clicks somewhere above the menu instead of on the menu.
