Hover set to nothing. Will play with it in future.
Default Win8.1 button.
Well, I put a fresh image of Win8.1 pro, and tried Media Center edition as well,
on a different hard drive as a test.
I can not duplicate the strange menu selection error,
where I have to click on desktop, to reset.
I tried CSM 3.6.8 as well as 4.0.2
I did find something in 4.0.2 version with default windows start button, that can trip me up.
I found out I'm sloppy with the mouse pointer!
With Windows magnifier on full screen view,
one naturally moves the pointer towards the edges of screen to move the
zoomed in desktop, around.
The only problem with that, is the Windows start button seems to latch on,
and won't release if pointer is moved close to bottom corner.
So even if pointer is moved away from corner edge to center of button,
it's stuck on that corner mode, waiting to be clicked,
and will always go to start screen, not CSM.
It has to be reset by moving off the button.
The whole start button visibly moves a few pixels to the right, as it gets triggered for start screen.
If pointer is moved to middle of start button first,
the button is stationary, and then clicking will always go to CSM.
So that explains why operation is worse when magnifier is used.
The best solution for me, on the clean drive is to replace CSM start button,
with something visibly different to see, if moved past the threshold. Just like in 3.6.8
As for my upgraded regular drive, with all my programs and files installed.
Don't want to start all over, will live with it, unless others get same issue, and a fix is worth while.
I have forced CSM settings to work correctly by:
Classic Menu-Left click - "Disabled active corner for start screen"
Start Screen - "Middle click"
Win-X Right click - "Right click opens Win+X menu"
CSM settings menu-no setting. Won't be able to access CSM settings menu anymore. Not a big problem.
Can always make a quick shortcut, and put on taskbar.
Works fine.
Thanks for bearing with me.
