Hey Fred, I feel your pain—losing that instant error feedback makes coding way slower and more tedious. Let’s walk through some targeted fixes to get those real-time error hints back up and running:

• Check Code Insight Settings (not just Formatter)
  The formatter you enabled is separate from real-time error checking. Head to Tools > Options > Editor > Code Insight:

  • Make sure Enable Code Insight is checked at the top of the panel.
  • Expand the Syntax Checking section and verify both Enable Syntax Checking and Show Error Hints are turned on.
  • Double-check the Error Insight sub-section too—ensure the relevant options for your language (Delphi/C++) are enabled.

• Reset IDE Configuration
  Corrupted config files often cause weird, unexplained IDE behavior. Close Rad Studio completely, then open a command prompt, navigate to your Rad Studio bin folder (usually C:\Program Files (x86)\Embarcadero\Studio\<your_version>\bin), and run:

  radstudio.exe -r
  

  This launches the IDE with a fresh, default configuration. If the real-time hints work now, you can gradually import your old settings from the backup the IDE creates automatically.

• Test in Safe Mode (Plugin Conflict Check)
  Third-party plugins can sometimes interfere with Code Insight functionality. Start Rad Studio in safe mode by running:

  radstudio.exe -s
  

  If the error hints start working again, disable your installed plugins one by one to pinpoint which one is causing the conflict.

• Repair the IDE Installation
  Missing or corrupted components might break real-time error checking. Open the Embarcadero Installation Manager, select your Rad Studio version, click Modify, then choose the Repair option. Let the repair process run its course, then restart the IDE.

• Verify File Type Associations
  Ensure your code files (like .pas for Delphi, .cpp for C++) are linked to Rad Studio’s native editor. Go to Tools > Options > Environment > File Types, find your target file extensions, and confirm the default editor is set to the Rad Studio Code Editor.

Give these steps a try in order—most of the time, one of them will bring back that instant error feedback you rely on.
