Tech. Note 1: Getting a debug trace

If you are having a problem with Guiffy, a debug trace may help us find the bug. First, edit the guiffy.lax file to write .err output to a file, Debug.err. Then, run Guiffy and reproduce your problem, and exit Guiffy. View the contents of the Debug.err file - created in the install folder. If the Debug.err file has anything in it, include it with your problem report.

Edit guiffy.lax, change the LAX.STDERR.REDIRECT line from:
lax.stderr.redirect=
to
lax.stderr.redirect=Debug.err
