Uncaught Error: Pty seems to have been killed already

In Atom + Juno 0.12, I have some error during 2 cases:

# 1. When I read a large CSV file

CSV.read(xxx) |\> DataFrame

Then REPL is frozen, does not accept any interrupts  
and then i press CTRL-J CTRL-K to kill Julia process, below error pop up:

C:\Users\ericche.atom\packages\julia-client\node\_modules\node-pty-prebuilt-multiarch\lib\windowsPtyAgent.js:160

# 2. Quickly Shutdown and Start a new Julia process

If REPL is interactive and responding, and I press CTRL - J CTRL - K to shut Julia down  
2 second later press CTRL - J CTRL -S → to start a new Julia process

then **the inline evaluation does not work**  
i.e. When I select my code and “CTRL - ENTER”  
REPL show nothing.

Status bar in the bottom of Atom show it is very busy.

there is a winpty-agent.exe process running in background and never stop…

I think this two issue are related…

FYI I am using the “Basic” mode in julia client. I cannot use cycler since I need to restart Julia quite often.

I also enabled Powershell Wrapper but the “interrupt” command never works and once REPL is running some process, it will be frozen…

I am using Windows 10.
