I have to use both the 8.5.5 and 9.8.5 clients.
I was able to have them on the same machine. However, after I open the 9.8.5 version, the host server list do not show up in 8.5.5 anymore. It appears that both clients are using the same servers.xml file. But, the 9.8.5 is using a different "encryption" for server names and whatnot; this is why they don't show up in the 8.5.5 version after I open the 9.8.5 version.
Does anyone know how to solve this? I don't even need to have BOTH clients opened at the same time.
