A more generic alternative to the above answers would be this simple script that I called "regular-scrollbars":
Save that someplace on your path, and then you can use the menu editor to add "regular-scrollbars" before any command you want (as long as it only has one argument - try
"$@" if you think you'll need more than one).
This means you won't have to make a new script for any other programs you want to revert to the old scrollbars.
I really like the bashrc alias example too though, you could probably make it more generic by providing a list of programs you want to revert and having bashrc loop over them, adding the aliases.
