You have not provided enough information for anyone to offer more
than a guess. For instance, you say the "Stop It" button is disabled.
Have you disabled it in your code or in Interface Builder?
I see that you have an -updateUI method ... could you be disabling
(as opposed to *enabling*) the button when this method is called? Do
you have the button connected to an outlet so you can say something
like [stopItButton setEnabled:YES]?
Again, all we can give you is my best guess with the information
you've provided.

Hello all,
in a document-based Cocoa project the window has several table
views and
two buttons
``Launch" and ``Stop It", corresponding to the following methods in
MyDocument.m :
-(IBAction) goOnAndOn : (id) sender
{
while (watchDog) {
[self goForward];
[self updateUI];
}
}
-(IBAction) stopItAll : (id) sender
{
watchDog=NO;
}
This does not work at all, because the Button ``Stop It" is
disabled when
the program is
busy. What is the proper way to do this ? Should I use delegates ? In
which class ?
