Nope. I could not save it, in spite of being logged in as administrator. (Windows 7/64)
I just got it done like this:
Windows assumed
Create new file. It'll be named sketch
Modify as desired and save it in the user folder and close
Navigate to the user folder and to the folder containing the newly created .ino file
Copy the .ino file.
Navigate to the bare minimum folder as illustrated above
Paste your new custom file to the folder
Rename the existing bareMinimum, I used 'BareMinimum orig'
Rename the new file to BareMinimum
Done
Thanks, larryd!
