How do I override the Leopard defaults to display sheets with an
alpha of 1.0?
My application uses a lot of NSWindow sheets - for a good reason.
I do NOT want a semi-transparent background, nor do my users.
Make the contentView of your window a custom view where you fill the
rect with a solid colour. I actually used this to get rid of the
pinstripes in Tiger, and it is not transparent in Leopard. I post
the code down here, though that might be superfluous as it is really
simple.

@interface PMPanelBackgroundView : NSView {
}
@end
#import "PMPanelBackgroundView.h"
@implementation PMPanelBackgroundView
- (void)drawRect:(NSRect)rect
{
[[NSColor colorWithCalibratedWhite:0.9337 alpha:0.98] set];
NSRectFill(rect);
}
@end
If the goal here is to be 98% opqaue, you'll want to use
NSRectFillUsingOperation instead. Otherwise, to reinforce the fact
that total opaqueness is desired, just set the alpha to 1.0.
