Dear Rupert
Your result for the message mytmp is strange
Hereunder is a small list of test
in a cmd windows, run rubens
in another cmd windows, try the following command
tasklist
tasklist /FI "imagename eq rubens.exe"
tasklist /FI "imagename eq rubens.exe" /FO list
tasklist /FI "imagename eq rubens.exe" /FO list | find "PID"
if a rubens.exe process exist, you should see successively
all the processes
only the rubens process
the rubens process presented by lines
the PID number of the rubens process
If this test works and the matisse launch crash, that means you have a problem in the line 205 of runmatrub.pl
$mytmp=`tasklist /FI \"IMAGENAME eq rubens.exe\" /FO list | FIND \"PID\"`;
regards
