Using Windows 10.0.17763.557 & Directory Opus 12.15 build 7102 (pro). Since the last Directory Opus update, when I startup Windows (or even simpler kill off the Dopus task), when I open a new Lister it goes into "not responding" every time for about 10-20 seconds and then recovers to be usable. This is happening on three machines all running the same versions.
As this is consistent it seems to be a new "bug" recently introduced.
I just noticed it is dong this with my Windows Server 2016 system also. This does not have any USB drives. Only happened since latest Opus upgrade. No pointers to network drives, listers startup to desktop.
It is not just Windows startup, if I stop the Dopus.exe task, every time it starts the same thing happens.
All other settings, taskbars, etc same as previous version that does not do this.
If you create a manually generated dump file of dopus.exe while it's in this "not responding" state and send it to us we may be able to tell what's going on.
