Hi all, I don't really want to bother you guys, I know that you have all very important developments ongoing. Actually I don't ask you to help me about this particular problem that I've found with the snapshot release of the Xserver/Xlib. What I would like to understand is if the technique that I'm using with the two threads is actually correct or not. Can I safely assume that my program does not works just because of a bug in the snapshot release ? There is a more correct way to do what I'm doing ?
I will be grateful if I could have at least some hints. Thank you very much in advance. My previous mail follow below.
