That's harsh - this is after all a VB forum, not a Synergy .NET forum. I'm happy to provide feedback but there is nothing to add. I use Synergy .NET in VS2013/Win 8.1 every day and do so very successfully. It appears EDIGUY is having problems, but without error messages there is little I can do to help or advise. If we have the errors/example code then I will certainly assist.
