This is a follow-up to Jim Krenz's question "Script to launch or

In one of my script's I replaced, this morning, the line ...
short name of (info for (path to frontmost application)) as text
with the line ...
tell application "System Events" to (name of (some process whose
frontmost is true)) as text
The first line always returns, correctly, the name of the
application which appears at the left of the menu bar. The second
line, under the right conditions, will return the name of my
application. But this isn't supposed to happen, since my application
is an FBA and its name never appears in the menu bar. ... The
'activate me' command does not cause my application to appear in the
menu bar or dock, so line 2 should NOT return the name of my
application ... but it does. If you use this in a script compiled to
an FBA, you should make it the first line, something like this ...
tell application "System Events" to set currentAppl to (name of
(some process whose frontmost is true)) as text
I haven't the slightest idea if there is a bug here. Perhaps someone
knows.
1. I'm betting you're using Tiger. Am I right?
2. Exactly how did you mark your application as "faceless"? Did you
use LSUIElement = true, or LSBackgroundOnly = true? There are
differences.
If you made your application a UIElement, then it does actually have a
"layer" in the UI, and can be activated even though you don't see the
menu bar change, so in some sense System Events returning it as
"frontmost" is correct. (System Events itself is a UIElement
application.) However, no one expects this -- the frontmost
application is the one with the menu bar, right? -- so we fixed it in
Leopard. "path to frontmost application" returns the menu-bar-
frontmost application in both Tiger and Leopard.
