Quality Insight is Borland's re-branding of the JCL OTAPI exception, combined with an interface to submit bug reports directly to QC. In a nutshell, it takes any unhandled exceptions that occur in the Delphi 2005 IDE, report a dialog - complete with stack trace - to you, and allows you to submit the bug report to QC. It's similar in concept to Windows' online error reporting mechanism. It's a very handy tool, and I believe it will help increase the stability of the IDE, since it gives R&D more information about bugs that pop up in the IDE.

Unfortunately, it looks like it is disabled by default during install (at least it was here on all 8 machines). To turn this useful feature on, run regedit.exe and set the following key/value pair in

HKCU\Software\Borland\BDS\3.0\Known IDE Packages

$(BDS)\Bin\exceptiondiag90.bpl = (Untitled)

If the value is blank, the package will not be loaded in the IDE. Therefore, set it to some arbitrary value, like "(Untitled)", restart Delphi, and you should be greeted with the exception dialog the next time you encounter an unhandled exception in the IDE.

Note: Be careful of using other 3rd party exception tools (e.g. madExcept and Eureka). You'll have to test for sure, but these other packages may end up consuming the exception before it gets to Quality Insight. If that's the case, simply disable the IDE package of the 3rd party exception tool.
