Is this normal? I have my computer set to go to sleep after being idle for a while. If I was connected to the ModelManager database before it goes to sleep, the connection is lost when I get back to my computer. What I found is that my computer turns off the LAN card when it goes to sleep (to save power). If I turn that option off, then I don't lose connection to ModelManager.
I've also found that if I unplug the LAN cable while I have Modeling and ModelManager running, obviously both stop working. Modeling, however, will automatically reconnect to the license server after I plug the cable back it; ModelManager won't reconnect automatically.
