I am concerned about the performance of Directory Opus. It lags terribly, and in some instances, simply will not respond for upwards of 10 seconds, if at all. When it does not respond at all, sometime I see an error message about a thread. Simply starting the application takes nearly 6 seconds. When I change directories or drives, that takes several seconds as well. And most attempts to right-click on an item for a sub-menu takes 8-10 seconds, and sometimes it never responds at all.
I am running with 5 internal drives and 3 networks shares. I am not sure if this impacts performance, but I thought I would mention it. I should also add that standard Windows Explorer responds just fine on my system. I really like DO, but its performance is making it unusable.
