jswat does not find source files others than in bin\-directory?

Hi folks,

I freshly installed Groovy 1.5.6 & JSWAT 4.3 (under Win XP); wrote a 
small test.groovy script which runs flawlessly in the groovyconsole.
Now when I try to debug this with JSWAT, the darn thing tells me:

"Caught: java.io.FileNotFoundException: C:\Program 
Files\jswat-4.3\bin\test.groovy (C:\Program 
Files\jswat-4.3\bin\test.groovy)"

Well, obviously, that's correct: My groovy-script is in "Z:\Groovy 
Scripts\" and I told my system so by setting a respective SOURCEPATH 
environment variable pointing to that directory -but to no avail.
(Yes, I may move the test.groovy script file manually over to the 
bin\-directory on C: which jswat expects, and it will work; but hey, 
that's a bad kludge: Whatever I change in the source file will be 
written to the script on Z: , so doesn't make it for debugging (=version 
on C:))
What it is going on here? How can I tell jswat that my scripts to debug 
reside on Z:\Groovy Scripts ???

Thanks!
