[tooltip] ie mousemove bug

[DBLaci]

In some cases with internet explorer, when the track: true, the mouse cursor flashes from default to hour-glass. I found that the mousemove event fires constantly, even if the mouse not moved.

i fixed the issue by moving there removeClass calls

remove position helper classes helper.parent.removeClass("viewport-right").removeClass("viewport-bottom");

to the else blocks of the following code:

check horizontal position if (v.x + v.cx < h.offsetLeft + h.offsetWidth) {

left -= h.offsetWidth + 20 + settings(current).left; helper.parent.css({left: left + 'px'}).addClass("viewport-right");

} else {

if (helper.parent.hasClass("viewport-right"))

helper.parent.removeClass("viewport-right")

} check vertical position if (v.y + v.cy < h.offsetTop + h.offsetHeight) {

top -= h.offsetHeight + 20 + settings(current).top; helper.parent.css({top: top + 'px'}).addClass("viewport-bottom");

} else {

if (helper.parent.hasClass("viewport-bottom"))

helper.parent.removeClass("viewport-bottom");

}

in short, these classes are removed only when they are set. I don't know why the removeClass triggers the mousemove event, but it does. (in ie) This workaround is working for me.

Thanks
