Hi Professor Savant,

Confirmation that it should work was what I was after, so after reading your email, I decided to write up a test app, and it happens there, too. This is the problem distilled to its simplest form. I welcome any feedback, mockery, etc.

If I use the option in (1) below, it works fine. If I use the option in (2), which is what I WANT to use, no animation occurs until after the mouseup happens.

-Chilton

- (void) mouseDown: (NSEvent *) theEvent
{
	while (1) {

        theEvent = [[self window] nextEventMatchingMask:(NSAnyEventMask)];
		if (([theEvent type]==NSLeftMouseDragged) ||
			([theEvent type]==NSLeftMouseUp) ||
			([theEvent type]==NSLeftMouseDown))
		{


			// (1) If I use this, it works fine. No zooom zooom though.
			//[button setFrameOrigin:[theEvent locationInWindow]];

			// (2) If I use this, it doesn't work.
			//[[button animator] setFrameOrigin:[theEvent locationInWindow]];

			if ([theEvent type]==NSLeftMouseUp) {
				break;
			}
		}

	}

}
