Now this is getting weird. I found that the setappcapflag function was still in vusrmacs.e. So I ran it from the command line, as described in the Beta thread.
Before that, when opening a project from the Project menu, the project name appeared in the Titlebar next to the SE icon. Once open, the bar changes to <filename> - <fully qual. path to file> - SlickEdit.
Now, I see SlickEdit next to the SE icon as the project opens. hmm. and then the title bar displays as before. unloading vusrmacs doesn't change the behavior.
Help for Functions doesn't describe how to unload a Function, that I could see.
