Other than looking in the Configuration dialog box?
Yes.
Copy your shortcut and edit the copy's properties to add a -debug after the command line entry. Make sure there is a space between the existing command and the -debug. Also, make sure there is no space between the - and debug.
When you run this shortcut, a text window will open and a ton of information will scroll by. At the end, it will tell you that all of that information is written to a MSDEBUG.TXT in your temp folder.
You can follow it line by line as it explains which CFG file it is reading and what variable is assigned and eventually there is a final total list of regular and hidden variables.
Sometimes, in the top portion, you might see something assigned one value and later i gets reassigned another value. Sometimes it is assigned to what ever is in another variable and that variable is empty. When that variable is finally assigned a value, the other variable is also assigned the value.
