Boy what a bad Idea.....
That said, I know of one bug that will help in some circumstances:
LoMem global $210 is the BootDrive.  This is the same as the System folder 
(as returned by SysEnvirns) except when you are the startup App in which 
case it is the App dir.  This is not a really good solution since if your 
app happens to be in the system folder it will fail.  

I take it that you are concerned not only with whether you are the 
startup, but whether you are actually running as the startup app THIS 
time(ie you could be the startup and quit and re-run not as the startup).  
If this is not the case then you could look at the startup file or the 
boot blocks or whatever.  This is probably dangerous, but I really don't 
know that much about it.
Maybe some of the managers are not initialized...doubt you could count on 
that because INITs may do any of these initializations.

Just curious, why do you want to know?

PS:  By the way this is an area about which I do not know much... so I 
make no guarantees about this particular post or its correctness.
