I was only able to reproduce your problem if you compile debugdemo 
without changing your working directory to the directory with 
debugdemo.ecl (and the other programs listed in the chapter).
For example, if you used 'File->Change to example directory' to change 
to the example directory, and then compiled debugdemo.ecl without using 
cd/1 or ThECLiPSe's 'File->Change directory...' option to change into 
the tutorial directory, i.e. you either used File->Compile... and then 
changed the directory in the file selection widget, or equivalently,
["tutorial/debugdemo"] in the query entry. This will compile the file 
*without* changing your working directory.

If you did this, running colour will show the problems you described. 
This is because debugdemo assumes it can find the other files in the 
current directory, and if they are not, then the execution fails.

Is this your problem? The tutorial chapter does say you should change 
your working directory to the directory where the debugdemo.ecl files 
are, but the debugdemo.ecl program does not actually check that this is 
the case. I guess I should change the program to be more robust to catch 
such problems.
