I was able to work on the Inter-Process Communication sandbox and I only had an exercise or two left to do. Now, I cannot open the sandbox for neither the

1. Inter-Process Communication; nor

2. kdb developer level 2 Capstone Project


I can still access and work on the Jupyter notebooks from previous modules. Any help with this issue would be appreciated.

Hi @proof 

Can I suggest restarting your server?

Go to File -> Hub Control and here you will see the options to Stop Server and Start Server again.

Let me know if this works!

Thanks.

I just did that and then saw your message. It worked, thank you very much!

I thought I had done something wrong to cause it to crash, but I just looked at the solution and it's the same thing. I ran it and now have to restart my server again. I am sharing in case this is a common issue!

Code (from IPC_Exercise_Solution) that seems to cause the crash:

handleBack `ID

Thank you for raising! I'll make sure to have a look at this :)
