ddd font size

Hi,

I tried to get the ddd font smaller, and must have made a mistake. Now the
font is so big, I cannot do anything.

DDD is installed on a Raspberry Pi running Jessie (Raspbian 8).

I tried the find command, but I cannot find the files or directory ddd is
installed on. My knowledge of Linux is not the best, and I cannot find the
parameters needed for the find command.

I tried removing and re-installing DDD, and the result is still the same.

Any help will be much appreciated.

Thank you

Johan Smit
