yup have thought about it..
but a normal timer at 1 second seems kinda to slow for it
and dunno how much resources a millisecond timer takes..
and it kinda appeared to me as being a cheap sollution
plus it doesn;t really disable the parent dialog , i would still be able to press the quit button on the parent dialog , causing errors when other timers try to update the 'Listen' Dialog while its already gone...
