I'm running Directory Opus on 10.0.0.0.4137 x64 on Win 7 x64.
Install ratdvd.ca/, navigate to ratdvd folder -> Directory Opus crashes (factory/default D.O. setup!!). (you should be able to reproduce this)
I pinpointed the problem to the ratdvd.exe file. When renaming to bla.txt e.g. D.O. does NOT crash.
I also have a D.O. config setup where navigating to a specific JPG file crashes the program. I'll try to find out what setting this exactly is and tell you and give you JPG file (it's not explicit material at all, so should be OK, no nudity at all, just might me a bit embarrising for me).
Hope this helps to improve program. Please tell me if you can reproduce 1. problem. Thanks.
