pyttsx always busy

[symsymmas]

runAndWait infinitely loop. I think that's because of isBusy function which always returns "True".

Can you post your relevant code so someone can try to reproduce this?

I've recently been getting the same problem - Related to threading module? Related to Python 3.6?

Yet to produce a "minimum faulty program" for a bug report.

The above two snippets show a working and non-working version of pyttsx on Windows. The non-working version involves a second thread.

Note: This is based on Julian-O\pyttsx, which has had a trivial change to setup.py, to use pypiwin32 over win32com, as it is compatible with virtualenv.
