Wow, this is an old post, but still applicable..
I have been using EmEditor through a few versions now and I keep waiting for this issue to be resolved.
I find that I open files on my laptop for review while connected to my work network. I finish for the day and go home, I open my laptop any try to work on or create a file and I find that the EmEditor is hung because it can’t find the network path. I have to forcibly close it and restart it to be able to use it. It can be a problem if I have files unsaved when I force it down.
This would be a good fix to implement. Thanks..
