Hello !

I have a little problem (or bug) which everyone can reproduce in a few seconds.
Just start the IB , drag some ColorWells one beyond the other and group them in  
a ScrollView. If you try this in the Test-Mode (or in the compiled version)  
you'll see that the ColorWells aren't displayed correctly. If you move the  
scrollbars fast enough all is okay, but if you get slower you'll miss some  
ColorWells. But they still there as you can see by clicking on the place where  
they should be.
Does anybody knows what happens or better how to solve this problem? 

Thanks for answers    Hans-Peter Geiser

I encountered this the other day and sent a bug report off to NeXT.  Here's  
my workaround....

---------------MyNXColorWell.h
#import <appkit/appkit.h>

@interface MyNXColorWell:NXColorWell
{
}

- drawSelf:(const NXRect *)rects :(int)nrect;

@end
-----------------MyNXColorWell.m
#import "MyNXColorWell.h"

@implementation MyNXColorWell

- drawSelf:(const NXRect *)rects :(int)nrect
{
	[super drawSelf:&bounds :1];
	return self;
}


@end
----------------
