Probe Basic is it compatible with Python3?

If you can find the error could you post it here.

Did you have Python2 or Python3 as the default Python on the machine? 2.8 would expect Python2 as the default.

I think Python2, but not certain.

I'll test tonight and start a new thread in QtVCP with the error(s).

Try this. helps sort out the default python issue.

Thanks for the tip.
Python2.7 appears to be the default version:

MILL@MILL:~
$ python --version
Python 2.7.16

I'll start a new thread over in QtVCP as this has moved away from QtPyVCP.
