hmm this didn't work but it was worth trying 
(I copied into wbstartup)
To end your drive clicks dowload this
http://aminet.net/package/util/cli/wildclickExtract it, copy the file 'wildclick' to your C command drawer (SYS:c/)
edit your user-startup by opening a shell and typing 'ed s:user-startup'
at the bottom of the file simply add the command 'wildclick'
Select save from the menu and then reboot.
There are lots of anticlick programs available but I believe that to be the smallest one.
The one I actually use is built into MultiCX, but if it's just the click you want to get rid of, then wildclick is the best solution.
