I enabled the X-Mouse feature on Win 7.
Its system option is "Activate a window by hovering over it with the mouse".
I hope CHS's Filter box (when it gets the focus) will not block X-Mouse. Please!
It not only blocks X-Mouse, but also blocks the Win key, and affects other hotkeys (e.g. after pressing Win+R, the Run dialog is not focused).
It also blocks the accelerator keys in CHS window, e.g. Alt+F for File menu.
And, when the Filter box gets the focus, and I press the hotkey to hide CHS, though CHS window is hidden, the focus is still seized by the Filter box (keyboard inputs still go there), unless I click another window.
At least, please don't auto-focus the Filter box when CHS window opens.
