Hi @Aigars,

Some guidance below for visitors to the topic. 🙂

There was a recent update and _error underlining_ was not working until the fix in Processing 4.4.7:

> [@Processing IDE 4.4.4 does not show line in error](https://discourse.processing.org/t/processing-ide-4-4-4-does-not-show-line-in-error/46915/24):

> Hi! We have just released version 4.4.7 which can be found here: [Release Processing 4.4.7 · processing/processing4 · GitHub](https://github.com/processing/processing4/releases/tag/processing-1307-4.4.7) This release features a fix to this error. Give it a try! Thank you and thank you @joshg for the fix! tadablue_heart blueberries Moon

Be careful not to delete the sketches you created!  
Create a backup if you choose to delete these.

User sketches are here:

I also had some error underlining issues too with VS Code and Processing 4.4.7 but it was related to _all my tinkering_ with VS Code settings! Entirely my fault in this case.

I did a VS Code restore for this and everything worked after:

> **[Uninstall Visual Studio Code](https://code.visualstudio.com/docs/setup/uninstall)**
>
> Uninstall Visual Studio Code and clean up.

I am careful now and document what works and able to restore easily to defaults.

VS Code is very much a learning curve for me as well!  
And still learning things about the Processing IDE.

I have multiple versions of Processing and it sometimes gets complicated.  
I have since learned to isolate each environment so they do not impact each other.
