[Click] Problem with clicky rendering

[david johnson]

Eric,

Thanks for the advice - I discovered the problem was with Ubuntu using
dash instead of bash. When I started clicky I had this error 

bin/sh: Syntax error: Bad fd number

it still ran - but the images were all on top of one another

But now it makes sense that it is a shell problem looking at the code
section you sent which executes the dot program via a shell call.

To fix it I just did the following:

sudo rm /bin/sh
sudo ln -s /bin/bash /bin/sh

Cheers
David
