GreaseMonkey has a function named "GM_registerMenuCommand()", which adds a menu to the GreaseMonkey "User Script Commands". This menu could be used to creat for example a configuration menu for that script.
However, if you have a plugin called Citrix Online Web Deployment Plugin installed (where did that one come from???), then it doesn't register properly and you end up with a greyed out "User Script Commands" menu.
Disabling that plugin resolved it.

One of the jobs I have at this moment is the parsing of PDF files. Very easy... convert PDF to HTML, convert HTML to text and then parse it. Only sometimes the PDF files are protected:
[~] edwin@k7>pdftohtml 3798b854f6245a5b98ec0344aefd44b1.pdf Error: Copying of text from this document is not allowed.
Luckely there is an easy solution for this:
[~] edwin@k7>pdf2ps 3798b854f6245a5b98ec0344aefd44b1.pdf [~] edwin@k7>ps2pdf 3798b854f6245a5b98ec0344aefd44b1.ps [~] edwin@k7>pdftohtml 3798b854f6245a5b98ec0344aefd44b1.pdf Page-1 Page-2
Mission accomplished! :-P

I don't know if it is Zopes problem, I don't know if it is Plones problem, but I do know that it was my problem. The problem description was simple: When entering events in plone, the time always jumped back about 10 or 12 hours. Editing these events made it jump back further...
The problem at the end was related to the way the functions in DateTime.py interpret the EST returned as the timezone. For example, this is the output of date(1):
[~] edwin@k7>TZ=Australia/Sydney date Sun Jul 30 19:33:36 EST 2006 [~] edwin@k7>TZ=EST date Sun Jul 30 04:33:30 EST 2006
So despite that the date function returns the Australian EST, the timezone EST reverts back to the US version.
And now the gory details on how to resolve this: Search for the file DateTime.py (/usr/local/www/Zope/lib/python/DateTime/DateTime.py on my machine), search for the definition of the array _zmap and in there, search of the keypair 'est':'US/Eastern'. Replace the est at the beginning to something else (I made it eest), then restart the Zope daemon et voila.

A customer called today, wondering why his Thomson Lawbook Online didn't work on his MacOS/X machine. It didn't work on Safari, nor on Mozilla and neither on Firefox.
Thomson Support didn't really show their cluefullness: Yes, it has Java installed. No, it's not a network problem. No, Internet Explorer for the Mac has been phased out years ago.
Now I do like the simplicity of Mac, but it doesn't really make debugging easier. Luckely, searching for "java preferences" showed me three applications with which I could display the JDK Consoles.
They showed this:
JTOC::init
java.lang.NumberFormatException: For input string: "142_09"
at java.lang.NumberFormatException.forInputString (NumberFormatException.java:48)
at java.lang.Integer.parseInt(Integer.java:477)
at java.lang.Integer.parseInt(Integer.java:518)
at JTOC.setBrowserInfo(JTOC.java:577)
at JTOC.init(JTOC.java:224)
at sun.applet.AppletPanel.run(AppletPanel.java:354)
at java.lang.Thread.run(Thread.java:552)Note It's now halfway August, and Thomson Online hasn't come back to me with anything else "Can you please make sure he has the latest JDK installed."
