Chrome processes stay open after usage

[TravelTrader]

First: I like the library very much.
But ... :)

I finish the usage with the webbot.Browser.quit() function.
But sometimes - even though I exclude all problem breaks by if and try...except - the many processes around chrome stay open. Even after the code is no more running.

And it's not the first time and not only one application. Several approaches have this problem.
Is the problem a general one?
What are the reasons?

Thank you.

Can you provide detailed code steps to reproduce this issue? Thanks.

Try this:

web = Browser()
web.quit()
exit()
