Thanks. It's hard leaving old habits behind.

I've got a custom view that has a transparent background created
with colorWithDeviceRed. Everything works ok until I resize the
window, which results in the app crashing. Any help would be
appreciated. Here's the code:
- (id)initWithFrame:(NSRect)frameRect
{
if ((self = [super initWithFrame:frameRect]) != nil)
{
BackGround=[NSColor colorWithDeviceRed:.50 green:0.50 blue:.50
alpha:.50];
-colorWithDeviceRed:green:blue:alpha: is not +alloc or -copy. That
means it's your responsibility to retain the BackGround object if
you intend to use it later, and to release it when you're done
using it.
//BackGround=[NSColor grayColor];
}
return self;
}
- (void)drawRect:(NSRect)rect
{
[BackGround set];
You're trying to send a -set message to an object that no longer
exists.
[NSBezierPath fillRect:[self bounds]];
}
