I'm using DOpus 8 now because 9 is too buggy to touch. Anyway, I've changed several of my default system icons (stuff like My Computer, Network Neighborhood, blank files which lack extensions, standard folder appearance, etc) and in DOpus they're all just back to XP default. I haven't been able to get past this in 8 or 9. Any ideas? What's funny is under preferences -> display -> colors & fonts, it displays what my icons really should look like in the example image, yet goes back to default in real lister panes.
What problems are you having in Opus 9? Have you reported them? I don't see any posts from you here about any bugs in Opus 9.
How did you change the icons?
