[rt-users] RT4 slowness

[Chris Hall]

Could you point me in the direction of where to file the bug report?

I've just replicated this on another box I have set up as a test server.. so
one was Debian, the other Ubuntu.  In both cases, I downloaded jsmin from

http://www.crockford.com/javascript/jsmin.c

ran:

gcc -o jsmin jsmin.c

and copied the binary over to /usr/bin, and chmod +x /usr/bin/jsmin

I then added the following line to RT_SiteConfig.pm

Set( $JSMinPath, "/usr/bin/jsmin");

which resulted in no errors generated, BUT breaks the interface in the
following way: (note the absence of menu at the top, and the always open
dropdowns)

On firefox you get the bonus of getting Links and Basics stacked together as
well
