Yes sir, Win 7 it is. Okay for sure. I'll definately take a note of that. I was planning on doing it sometime soon, but if this fixes the problem then I won't reinstall FSX for a while. I'll report back when I get that .dll taken care of. Thanks for your help Kenneth! Much appreciated.

So turns out, I didn't even have to delete the .dll file. I just reinstalled my Turbine Duke because a lighting issue was occuring with the panel and now all seems well. Why is stuff so complex these days?
