Processing IDE not checking for errors after startup

[ngelpie]

Description

Even though i have enabled "Continuosly check for errors" and "Show warnings" in my preferences, Processing does not show any errors or warnings when i am writing new code directly after startup.

Preferences settings

Expected Behavior

Processing should always display user feedback before I run the program, i.e. for incorrect datatypes, type mismatches or missing brackets.

Current Behavior

Instead, I dont or inconsistently get errors and warnings before I try to run code after startup.

No warnings or errors displayed before running code

After that, it correctly displays errors and warnings.

Correct error and warnings display

I´ve deleted the preferences.txt file and even reinstalled Processing, which didn´t fix the issue.

Steps to Reproduce

• Sadly, the issue is hard to reproduce, since it doesnt seem to be caused by my code and it only occurs on my PC.

Your Environment

• Processing version: Processing 4.1.3
• Operating System and OS version: Windows 10 Pro, 22H2

Possible Causes / Solutions

I suspect it is caused by something like a corrupted preference file which was not deleted, even after reinstalling.

you should check for any remaining folders or any saved data which contains the corrupted file and clean that data. Take a backup of your data before that.
