You also wrote the MW for the Tk, but not really much else.
Right now, your main problem is that the detailed feed coming out of perljobs is giving "not well-formed" errors when XML::Simple looks at it, and similar errors when IE tries to look at it. Have to figure out what I'm doing wrong with the RSS feed. (The normal one didn't seem to have issues, but you only looked at it once or twice.)
Figure out something with this, even if it means using XML::Parser.
Work out the rest of the Tk, too. Think about using the Form manager this time. Pack's quick, but kind of unwanted. Eh, we'll see.
