Wow! I appreciate that you took a moment from your vacation to answer! I will look for that and see what I can do, and otherwise wait until you are not on vacation any more to ask more questions!
I am using iSphere 3.5.3r in RDi 9.5.1.2 in a Linux VM (9.6.0.6 has been nothing but a pain.) The Linux is Lubuntu 18.04 LTS. One problem I am having is when using the TN5250j feature, I am constantly losing my session, which I believe is due to disconnects happening from idle timeouts. Is there any way to prevent this?
