Same issue. (Though not, I guess, for pyexpat). Not all COM objects are used in web servers. Some are used in GUI contexts (aren't Word and Excel and even IE really mostly COM objects these days?). > > It's annoying. > > > > I have noticed, however, that you can use os.putenv() (or assignment > > to os.environ[...]) to change the PATH environment variable.

Yes, that's a problem, especially since it appears that PATH is searched *last*.

Hm, I would think that the danger of temporarily changing the current directory is at least as big as that of changing PATH. (What about other threads? What if you run into an error and don't get a chance to cd back?) > As for the others: probably not; can't see how; yes. --Guido van Rossum (home page: http://www.python.org/~guido/)
