Hello, Answering Simon's question: No, on 16.04 and 14.04 everything is OK !!!! The problem started (as it is mentioned by "prrvchr" up above at message #3) from Lubuntu release 17.10, which I can not confirm, since I never used 17.10. I use mostly the LTS releases. But I can strongly confirm the problem with 18.04. I help you of course, the problem is also mine, since I'm a Lubuntu fanatic :) and I really want it to work well.
To Walter: Maybe, but I can only tell my experience, Thunar produces just the same kind of freeze as PcManFM. Trying Thunar in original Xubuntu Bionic I could not recognize the freezing, however I don't like Xubuntu. There are many other hard things with that... which are always leading me back to Lubuntu. :) But what I found, I was able to upgrade PCManFM 1.2.5 to the version 1.3.0 (comes with Cosmic) from Lauchpad.net This new version can use Bionic's original Libfm 1.2.5 without any problem. I've used it about for a week and THERE IS NO MORE FREEZING. EVERYTHING IS WORKING WELL. I'm really curious what is the difference between 1.2.5 and 1.3.0 ? Caja also works with Lubuntu Bionic well, without any problem, no freezing. I have only tried Lubuntu Bionic yet.
