Another Eclipse Question with Python

[Stan Cook]

I followed the help instructions to set a watchpoint for a 
variable, or at lest I tried.  When I hilight the variable 
and go to the run menu, the "toggle watchpoint" is grayed 
out and can't be selected as specified.  Is this Python 
related only?  Just wondering, I want to use the software 
with all of the features it allows if possible.

Thanks....
