Thanks for verifying that for me, Patrick. I was hoping it was just something not working on my end.
I tried editing the file in the BGC1 folder and still had the same issue. But then I got to thinking... I'm in Vista.
So, I remembered Vista's unusual way of handling files in the Program Files folder. I had to edit the setting.txt file that Vista created in this folder...
C:\Users\[UserName]\AppData\Local\VirtualStore\Program Files\ProSIM Company\Battle Group Commander Episode One
Works great now!
