Symptom is like that:
or sometimes lister has only toolbars visible but the area where files/directories should be displayed is blank.
Tray icon is not responding too. Hang escalates i.e. after some time other listers stop responding too.
The hangs may or may not be related to the presence of USB HDD enclosure that has a bad habit of turning enclosed HDD into sleep mode quickly.
I did not experience such hangs while using DOpus 12. The enclosure was connected at this time too, albeit with different HDD enclosed.
