Summary: Mouse Y is off by 100 pixels in some fullscreen games
           Product: Wine
           Version: 0.9.48.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: minor

        ReportedBy: [e-mail]

This is a bit difficult to explain, but I'll try anyway.

Some of the games created with so-called "Klik products" (available on
Clickteam.com) switch to fullscreen mode when they start. This is no problem,
except that the following happens: the position where you see the mouse is not
the same position as the game reads the mouse position in. The actual mouse
pointer is always ~100 pixels below the things happening in the game.

Example: there's a button. You want to click it. You can't, it doesn't do a
thing. You move the mouse a bit lower in the application. Suddenly, you CAN
click the button, even though your mouse pointer is ~100 pixels below the
actual button.

I don't know of any other way to test this bug than to play a Klik game.
"Eternal Daughter" on http://www.derekyu.com/games.html does this thing when
you press escape during gameplay and try to press "continue" or "quit".

(Side note: small graphical glitches tend to occur when I move my mouse lower
than the visible screen.)
