I was hoping that this behaviour would be solved with the solving of the bug I logged a while ago, but I now (version 0.36.1) encounter this problem far worse than before. I'm not able to reproduce it.
The process takes up about 50% CPU, and then it just doesn't react for a few minutes. I either have to kill it, or have to wait (some 5 minutes) and hope that it works again.
I have switched off the autoimport nzb, and I have selected a directory that does not have any subdirs that autoimport nzb is pointing to. What I mean it was switched on, configured that directory and then switched off. That way I was hoping it would not browse through numerous directories.
Does anyone else encounter this?
