\b0 operator (dx dy adjustmouse) and getting weird results.\
\
A: This is a bug. You must add 832 (the height of the screen) to dy for this operator to work properly. This bug also affects
\b PSadjustmouse()
\b0 . So that your application can use this workaround without breaking in future releases of NeXT's software, NeXT will probably retain the current behavior of adjustmouse, and implement the correct behavior in a new operator with a similar name.\
\
In any case,
\b adjustmouse
\b0 should be used with discretion, as user-friendliness requires that the user always feel in control of the cursor position. See "Manipulating the Cursor" in Chapter 15 ("Window Server Background") of the Technical Documentation.\
