I may be able to make use of that, although the window is not titled with the module upon startup, only upon switching, sigh...
Interesting... I just had to test it, and on OSX, the module name is always there (Library / Develop, I never use any other modules). Maybe it is one of the many Windows-only bugs?
Maybe the module name in the window title only disappears when the app loses focus. I thought I'd seen it disappear at other times too, but I could be mistaken. (seems to have nothing to do with startup - my mistake).
UPDATE: caught it: If I minimize Lightroom, then maximize it, the window title just says "Lightroom" (no module name). Some places I click, e.g. on a photo, it doesn't change, other places I click - it changes to show the module name.
