How to tell if I am in the IDE?

[Brian Maher]

Hi Folks,

Is there any way (in a script) to tell if I am running in the IDE?

In particular, I want to have a standard preOpenStack script that sets 
the style of the stack to modeless (to obtain the standard OS X 
background for the stack).  Unfortunately just putting that statement 
into the stack flips it to modeless style when I open it in the IDE 
(and it is annoying to have to flip it to toplevel every time I want to 
edit it).

Thanks, Brian
