message box and opacity

[tomoose]

I tried a search but can't find what I'm looking for.
I have the instructions for moving the message box and permanently placing it where I want it and making it permanently transparent but these instructions apply to 1.4
When I opened the ...menu.ini file to make the changes it appeared to me that the 1.5 version of the file was different which made my original instructions suspect and I didn't want to screw anything up.
For 1.5 what are the lines I need to change to;
a. Move the message box to a position I choose,
b. Make the message box permanently transparent, and
c. Get rid of the opacity slider altogether.

Thanks
