David,
thanks for reply.
Sorry, the project is in the middle of developing, and not lunched yet.
Btw, I found the reason that why the input is disable.
--------
Timeline._Band.prototype._onMouseUp = function(innerFrame, evt, target) {
this._dragging = false;
this._keyboardInput.focus();};
--------
the custom input will work when I comment out the red code. of course it wil break the
shortcut function.
cheers,
Yaou
