Hi, first of all, thanks for the good work done with Juno!  
We found a peculiar behavior when running our code wiht the newest version of Atom.  
Whenever we want to open a excel file from Atom with this command:  
`run('cmd /c start chrome.exe') `  
The following error message appears:  
 ![atom](https://global.discourse-cdn.com/julialang/original/3X/3/7/376ab23594e34999a2c34490699b2a6dbdf5e69b.png)  
And in the following, whenever we switch the view from REPL to the editor or in a different view of Atom a new instance of the error appears again.  
This error occurs under Atom 1.30.0 (in 1.26.1 it works without errors). Julia Client is version 0.7.6 and the operation System Windows 10.  
I was wondering, if there is a way to get around this, or if using an older atom version is the way to handle this?  
thanks

I can’t reproduce this locally –

```julia
run(`cmd /c start firefox.exe`)

```

works fine for me locally. I suspect this happens because of an invalid working directory, so it would be interesting to know what `pwd()` returns. Do you have any projects open in Atom (i.e. is there something in the `Tree View` under `View -> Toggle Tree View`)?

@uwechsler Did you try `run(`cmd /c start chrome.exe`)` instead of `run('cmd /c start chrome.exe')` (note the different ticks)?

Yes, I used the backwards ticks in my code. I just had trouble displaying them in the post.

You were totally write. Looking at `pwd()` enabled us to solve the problem.  
The working directory was a folder on the server and not a local path.  
After changing the working directory to a local path, the error disappeared.
