| Apologies for being vague. As I mentioned earlier, it also happens to the QT waterfall sink. When I was using the WX GUI, the same two sinks failed. Here’s the detail:
Executing: /usr/bin/python -u ~/Documents/top_block.py

Thanks for the help.

There's no such thing as "the Qt4 runtime error". Please send us the exactly what you're getting. This mailing list sees a couple of thousand emails in 3 years, so really, we'll need you to tell us what you're reading as error *in verbatim*, and a link to the mailing list archive post (or at least the exact date and subject line) to figure out what you're talking about.

I was hoping 3 years may have provided a solution since those QT blocks are so basic (frequency sink, waterfall).
I’m hesitant to switch to 3.8 since I don’t know if my OOT items will work, took me forever to get working, and my project is due in one week. But I’ll try on a VM tonight and see.
Thanks for your help!

Hi Carlos,
I saw mention to this error
not quite sure what you're referring to. What error?
WX not working on every platform and us not having adequate knowledge
to repair it was the reason to remove it from GNU Radio, so my
recommendation really is using Qt instead.
Also, instead of the oooold GNU Radio 3.7.11, I'd recommend you get our
release builds:
uninstall your old GNU Radio, and then run
sudo add-apt-repository ppa:gnuradio/gnuradio-releases
sudo apt-get update
to get GNU Radio 3.8.
Best regards,
Marcus

I saw mention to this error in 2017 in the archives and the fix was a delete and install. This is running Ubuntu 18.04 with GR3.7.11-10. The weird part is that WX FFT does not work and none of the frequency related QTs either. The others do.
Any idea how to fix that besides remove and re-install?
v/r,
Carlos
