Hi all  
I am having issues with a code snipped in REPL.

As seen in the video the REPL hangs (or at least it is VERY slow) at two lines.  
Surprisingly the first line is a comment line. The other line with the issue is the `driver.get` line

All I do in the video is pasting the entire snippet into the console (right click)

I can reproduce this on another windows machine.

BTW: VS code crashes when I run the driver.get(url) row.

Any idea how I can fix (or debug?) this?

here is the code snippet.

```julia
using InteractiveUtils;
versioninfo()
using PyCall 

webdriver = pyimport("selenium.webdriver")
#driver = webdriver.Chrome()
driver = webdriver.Firefox()

url = "https://www.dell.com"
smt = driver.get(url)
versioninfo()
0

```

I don’t have any answers, but I wonder if it’s related to this:

> Hello, for a long time now I observed a strange repl behavior, which I always [contributed to emacs + vterm](https://github.com/tpapp/julia-repl/issues/151). However I now realised, that it also appears in different terminals (iterm2 on mac and windows terminal/wsl) so it seems to be related to Julia itself. The problem is, that pasting code into the REPL is much slower when pasting while the repl is busy then when pasting while idle. Steps to reproduce: open julia --startup-file=no past longish text: appears instantly call some function w…
