Re: Puzzle about ExtSelectClipRgn?

[Changhui Liu]

Dear Thomas:
It should be :
TRACE("After ExtSelectClipRgn:%s\n", wine_dbgstr_rect(&dstbox) );
I want make the output clear so I remove the  wine_dbgstr_rect(&srcbox), but I forgot remove the second %s. 
Thank you.

The second %s here will print random memory.
