No automatic refresh in the lister after restoring a saved configuration

Because I had another problem I installed Dopus completely new at first 13.10 wich I had before. I restored my saved configuration from two months ago. After that, the refresh of the file list doesnt work. I tried it ta second time with 13.10.2 Beta with the same result. I have to hit F5 to see new files in the folder. I have a lot of custumisations and don´t know how to get it back without restoring it or without to have a lot of work. In the Windows Explorer the refresh works. I know, there were earliear threads to this topic and I know that Leo sad, that refreshing shoud definiteley work. What should I do?

Thank you for your answer,Leo! It was indeed the no_external_change_notify. It was set to true. I don´t know when I did it. May be I changed it in my attempts to prevent those flickering folder tree which I have from time to time, which I mentioned in another thread. I tried all your suggestions in that case, but from time to time I still have this flickering folder tree. But I can live with it.
