AS3 Multitouch text field

I’m doing some application on the multitouch, everything is working find, everything can be rotate, expand (pinch) but only one problem…

all my text field disappear when I rotate it… but somehow the textfield will reappear when I rotate it back to its original angle (180 degree)…

can anyone tell me what to do so that my textfield will not disappear when I rotate it?
