We did hear back from Microsoft, and it's turned out to be an issue related to the security in Windows. Long story short, our hooks run with high integrity, and the Directory Opus hooks run at a lower integrity. Unfortunately Windows won't pass hook messages from a high integrity hook to a lower integrity hook for security reasons.

We're currently working with the Directory Opus devs to try and find a solution, but in the meantime, there are a couple of workarounds:

• Since the hooks are Last In, First Out, if you make sure that Directory Opus is launched after DisplayFusion, it will get the hook messages first, and then send them off to DisplayFusion when it's done.
• Disable the options under the Settings > Window Management > Mouse Management section in DisplayFusion.

I'll post an update in the other Discussions topic when we have more news on whether we were able to get a solution going between us and Directory Opus

Thanks!

No problem, we'll keep you posted if we do come up with a solution!

Alrighty! We've just released a new DisplayFusion beta version (http://www.displayfusion.com/Download/Beta/) and the Directory Opus devs have also released a new beta that fixes this issue (http://resource.dopus.com/viewtopic.php?f=1&t=20153). Please let us know if you run into any trouble after updating.

Awesome, glad to hear it! A big thanks goes out to the Directory Opus team for working with us on this issue, and for issuing their new beta so quickly as well
