# Description

Handle the mouseUp message to perform an action when the user releases the mouse button after clicking.

The mouseUp message is sent to the control that was clicked, or to the card if no control was under the mouse pointer.

>*Note:* If the user clicks a transparent pixel in an image, > the mouseUp message is sent to the object behind the > image, not to the image.

The mouseUp message is sent only when the Browse tool is being used. If an unlock field is clicked with mouse button 1 or 2, no mouseUp message is sent.

If the mouse has moved outside the control that was originally clicked before the user releases the mouse button, the mouseRelease message is sent instead of mouseUp. If the click is the second click of a double-click, the mouseDoubleUp message is sent instead of mouseUp.

>*Tip:* If the user clicks several times in rapid succession (for > example, if the user clicks an "Increase" button that increases a > number by 1), some of the clicks may send a mouseDoubleUp message > instead of mouseUp. If your script only handles the mouseUp > message, these accidental double-clicks will be lost. > One way to prevent this is to install a handler in an > object that's further in the message path, to re-send > double-click|double-clicks>:

on mouseDoubleUp if "on mouseUp" is in the script of the target and \ "on mouseDoubleUp" is not in the script of the target then send "mouseUp" to the target end if end mouseDoubleUp

If the user double-clicks an object whose script contains a mouseUp handler but no mouseDoubleUp, the above handler will automatically send a mouseUp to the object so the second click can be handled normally (instead of as a double-click).
