If you work with V2 components in Flash, this tip will surely help you out some day: when using V2 Components such as a Combobox, you may find your buttons no longer work correctly. Overall, this manifests itself by not being able to click more than once on a button. Before you can once again click on the button, you must first move the mouse again. Especially with navigation buttons, on which you are usually click-click-click-click-click-ing, this is less than optimal.

This is appearently caused by some components which are not playing nice with a component’s focus. The fix is relatively simple and disturbing at the same time:

In the onPress handler of such a button, you must include the following:

Selection.setFocus (this);

A focus rectangle now appears on every button, and to remove that, you use the following:

this._focusrect = false;

It is also possible to apply this to all buttons at once:

Button.prototype.onPress = function () (
this._focusrect = false;
Selection.setFocus (this);
)

This will not be an option in most cases however, unless you rigidly commit yourself to overriding only a button’s onRelease handler.
