    Hi Jan,<br>
    <br>
    Can you please repost your patch together with a description of the
    problem and your approach to fix it.<br>
    <br>
    I was not subscribed to that list back when you have posted it, and
    so may some others, who may be able to move this thing forward. You
    may also post a link to the specific mails/threads in the
    mailinglist-archives if that'll help with understanding your patch.<br>
    <br>
    I'll look at that then.<br>
    <br>
    I have some other issues with sequence numbers, and I think we need
    to solve that on a design level.<br>
    The essential thing is that the protocol transports only 16-bit
    sequence numbers, but server and client work with at least 32-bit,
    sometimes 64-bit sequence numbers. What I've seen so far in the code
    looks like heuristics which may fail in some cases. Maybe I am
    missing something. In any case, I want to see your problem analysis
    and your proposed fix before I propose something.<br>
    <br>

        I already forked it for myself a couple of months ago. As long

        have no real issue... except for an uncomfortable feeling that

        Now, when somebody would want to run the application on their

        to tell them to downgrade their xlib to 1.3.3 and file a

                                                The problem is that
                                                reviewing this patch is
                                                *really hard*. The last<br>
                                                time, I think I spent a
                                                solid couple of days
                                                thinking about this and<br>
                                                making sure I'd caught
                                                all of the cases. I'm
                                                still not sure it's
                                                right,<br>
                                                but I guess it's
                                                probably better than
