    GetCursor pos troubles

    Okey dokey I'm having some problems with GetCursorPos, it's giving me really bad coordinates... or maybe it's something else I'm unsure.

            if(sel[0] == 1)
        case WM_LBUTTONUP:
            if(sel[0] == 1)
              POINT pos;
              sel[0] = sel[1] = 0;
    sPos is defined at the top to keep it in scope for WM_LBUTTONUP.

    Did you declare it as static? If not, chances are it'll contain garbage values for the UP message.

    Are you intentionally allowing case statements to "fall through" to the next case?
    Missing some "breaks" perhaps?

    Yeah I had fixed that after posting, it was messing up some other switch's as well ... I tried setting static POINT pos; but still it's going weird.

    It's actually not realy sPos that's wrong I think, the start of the retangle is usually right but it's the width and height that are way out of whack.

    [edit:] Doh! Of course, so stupid!

    pos.x -= sPos.x;
    pos.y -= sPos.y;

    I wasn't actually adding distance relative to sPos relative to parent.

    Thanks anyways!
