JBuilder IDE used to show red error mesages while editing my code

[Ulvang]

Can you answer this?
My JBuilder editor used to show what would be compiler errors in red in my IDE as I was typing in my source file. This was really handy. 
Now it won't show any errors until I compile. Did I turn this feature off somehow? If you know how I can turn it back on, please let me know....

Thanks!!!

It sounds like you turned it off

To check go to Tools->Preferences

Then to the Editor section, in the part Error Indication make sure all 3 tick boxes are selected, that should highlight errors.
