No, I don't think that applies to me. At least, none of that rings a bell as something that I did after installing SE2011. Also, I don't have title_change.e anywhere in my SE2011 install, nor could I find any reference to setappcapflag anywhere in the /Applications/SlickEdit2011.app/Contents/macros directory, nor does it (or any title* command) show up as something which can be run from the SE command line or in the list of Slick-C definition list.
To be clearer about what I'm talking about, attached are screen shots of my SE2011 titlebar vs my SE2012 titlebar. It could be that the post you linked to above *does* have relevance to my issue but I just am ignorant of how (and, again, my memory fails me as to whether or not it's something I did previously).
thnx,
Christoph
