Hello,  
When I use RF to execute several tests from a shell windows, I have many errors (but they don’t stop the execution so I think it’s only warning).  
Someone has already seen this kind of errors ? And how can I fix them ?

Thank for help !

This is usually seen with Windows and running SeleniumLibrary with Chrome browser. Those are warnings, but usually do not harm the test execution.
