It's no surprise that SBCL works best - it's what

most McCLIM hackers

use. Also, it has good performance and implements

CLOS well, which is

important to McCLIM. Clozure CL is also supposed to

be good, so I'd be

interested in hearing the specifics of the error you

got (backtrace?).

With Clozure CL the only command that works in the listener's Filesystem menu is 'Up Directory'; everything else gives me this -

Error: value PATHNAME is not of the expected type LIST. While executing: CCL::FRAME-SUPPLIED-ARGS, in process repl-thread.

You can set the environment variable for Emacs (M-x

setenv)...

I'd tried that, but it still errored, asking if I wanted to use the local unix display.

It is normal for McCLIM apps to be slightly sluggish

at first, because

the CLOS caches need to be filled the first time

generic functions are

called. Successive invocations of the program should

start up

faster. A pause of an entire minute is highly

unusual, however. Which

version of SBCL is that?

When I run it with Clozure CL there's no delay at all. Only with SBCL. I'm running version 1.0.2.

How does it hang? Does it take up all available CPU

time or block?

McCLIM works on CLISP on Unix, so the implementation

itself should > not be a problem.

Yes, CPU on the Windows machine is 100% at that point. I'll have a go on my laptop, which runs Vista, see if that's any better.

Thanks, Chris
