Hi,
althuogh 4.17+ are more stable under some configuration, take in mind that it is more heavy that the 4.16 one.
I've used from a life the 4.16 with a 040 CPU because the 4.17+, had a slow scrolling.
Now with a 060 CPU, DirOpus 4.17pre20 works like a charme.
Install the dopus.library-ConfigOpus and the modules that comes with the archive.
Ciao
