I have been getting the following messages in the console window while my 
program is running...

Wed Aug 15 11:13:51 charlie-dickmans-mac-pro.local Mah-Jongg[4416] <Error>: 
CGContextSetFillColorWithColor: invalid context 0x0

Wed Aug 15 11:13:51 charlie-dickmans-mac-pro.local Mah-Jongg[4416] <Error>: 
CGContextFillRects: invalid context 0x0

I have isolated their source to the following code...

        [[NSColor whiteColor] set];
        [die1 drawInRect: iDieDrawRect
                          fromRect: imageRect1
                         operation: NSCompositeSourceOver
                          fraction: 1.0];
        [die2 drawInRect: jDieDrawRect
                          fromRect: imageRect2
                         operation: NSCompositeSourceOver
                          fraction: 1.0];

What can I do to eliminate these errors? I know the simple answer is to make 
the context valid but I don't know how to do that.
