I'm using the default Beamer theme because I like how it looks with the beaver color theme. However, the only thing I don't like about it is that blocks do not have a box around them. I like the block style from the Frankfurt theme, but I don't quite want to use the whole Frankfurt theme as it changes some things I like about the default theme.
Is there any way I could use the Frankfurt theme for just blocks, and keep using the default theme for everything else?
Thank you.
