Remote Connection to Toad

Hello there,

I have an issue with a user who whenever he tries to remote desktop over to his work computer from home, his queries will end and he has to shut down TOAD. Is there a setting in TOAD I can do to prevent this from happening? Does Toad not like to have an external IP Address interupt? Any help would be greatly appreciated. He is using Toad 11.5 for reference.
