Scratch

Could you describe a bit more? Like put a screenshot(just post a link to a picture)? What happens what you try to save or load a project?

Reinstall is all I can think of, right now.

I'm having a similar problem.  When I click either the floppy-disk icon or the Save option on the File menu I get a pink dialog box entitled "Message not understood: findTokens:".
There's a screenshot here:

This is on a new install, so it's possible that I didn't do something right when installing.  (I've been a Linux user since 1998, but I've never worked with Smalltalk before, much less Squeak or Scratch.  Most of my object-oriented programming experience is with Inform -- unless you count Perl5 as "object oriented", but I tend to treat it more as impure functional.) 

I'm running Debian 6.0.1 (squeeze), on a pretty standard 32-bit PC.  The squeak vm is from the Debian package, squeak-vm, version 1:4.0.3.2202-2.  I extracted the Scratch source tarball to /opt/scratch, and I'm using the following command line:
/usr/bin/squeak /opt/scratch/Scratch.image -plugins /opt/scratch/Plugins -vm-sound=null
The directory /opt/scratch/Plugins contains seven files.

The user I'm running as does have write permission on /opt/scratch as well as /opt/scratch/Projects and /opt/scratch/Scratch\ Projects.  If there are other permissions that I need, where can I find documentation on that?

I can't help feeling that there might've been something else I should've done when installing, other than just plop everything in a directory, but I don't know enough about Squeak to have any idea what.  The README file that came with the "source" tarball didn't seem to have any information at all about building, just stuff about setting various options.  There was no configure file and no INSTALL.txt, so I wasn't really sure what else to do.

There was a Makefile, so I ran Make, and it _seems_ to have completed successfully (although there were some warnings), but when I tried to make install, make says "No rule to make target 'install'. Stop."  Is that normal for Scratch, or has something gone wrong at the make stage? 

Should I post the output of make?  Why not?  Here we go...

Anybody see anything I missed, or know of anything else I need to do to complete installation?
