This is not a bug in Syn, but a bug in a different
application caused by something Syn is doing.
Syn.exe seems to have a conflict with TCServer.exe, a
program which is part of Microsoft's Windows XP Tablet
PC Edition. While Syn is running, TCServer.exe will
eventually have an application fault. I have not seen
this happen except while Syn is running.
I doubt Microsoft will ever fix their bug (or admit
they have one), so I hope it might be possible to fix
Syn so that it doesn't cause this problem.
