Huh, go figure.

If there is anything else I can do to diagnose this, I'll be glad to do it. (Higher level of debug tracing?)

I'm wondering almost the same thing. How can I get more debugging information to send back to you about why the client is seizing up. I've tried attaching gdb to the running synergyc process, but I get this: Reading symbols from /usr/bin/synergyc...(no debugging symbols found)...done. Is there another build that I can use with the dbg symbols in it, like most Ubuntu (and Centos) packages have a separate -dbg or -debuginfo package that you can install to give you the debugging symbols neccessary to get a backtrace. Do you have such a synergy-dbg package, or do we need to build from source with the debuggging flage enabled, or something?
