Michael,

I'm guessing the problem is the way you are setting your adjustedHeight. Any NSTextView that you see in your interface is actually composed of three views, an NSScrollView which manages the scrollers, an NSClipView which clips the content view, and the NSTextView itself. Thus your NSTextView could be 10,000 pixels high, even though all you see in the interface might be 100.

When you set your adjustedHeight variable, you might try the following:

float adjustedHeight = [[clockView parentView] bounds].size.height * 0.8;

This will set the adjustedHeight by the visible height of the NSTextView ([clockView parentView] will return the NSClipView), rather than the overall height of the NSTextView content.

For more information:

For some reason the value the adjustedHeight reports size goes huge
when resizing the window(the window actually doesn't grow as large is
it reports it does), resulting in the font increasing in size
exponentially, much larger than the NSTextView. Doesn't happen when I
comment-out the errant line(marked).

any ideas would be appreciated.

- (void)windowDidResize:(NSNotification *)notification {

float adjustedHeight = [clockView bounds].size.height * 0.8;
NSLog(@"adjusted height:%f",adjustedHeight);

timerFont = [NSFont userFontOfSize:adjustedHeight];// causes the size
issue
[clockView setFont:timerFont];
NSLog(@"resize");

}
