Optimetrics export_to_csv inconsistent behavior and failure

[sdesharnais]

The export_to_csv() method in an Optimetrics setup exhibits inconsistent behavior:

optimetrics_setup.export_to_csv(file_name_and_path)

I can run the same test over (strictly identical, I'm not touching anything other than the "run" button) and over and sometimes they will run smoothly, sometimes they will fail. Oddly enough, the tests will consistently fail for the same 2 optimetrics setups. These setups involve 2 sweep variables but that may not be what distinguishes them as other 2-variable setups consistently run fine. On the other hand, single variable setups consistently run smoothly.

I'm not sure that this is a PyAEDT issue or a Windows issue? Any thoughts?
