I know there's been a problem with Ltk on WinXP, but I've just tested it on Vista and it seems to run fine. Here's my setup - Sony PCG-7Z2M Laptop Windows Vista Home Premium Clisp-Win32 ActiveTCL 8.4.18.0 I'm going to test again when I've set up Cygwin on that machine, so that I've got a decent asdf-friendly environment (just loaded ltk.lisp for that quick test). Will also test with SBCL. By the way thanks Peter on an absolutely terrific program. Best, Chris ___________________________________________________________ Yahoo!
