ERegistryException in the Delphi Debugger

Valid from List & Label 8
When using List & Label with Borland debuggers an exception of class ERegistryException might be raised. This Exception is only raised when working with the debugger.

The reason is that the HTML extension module tries to read the current machine's proxy settings from the registry. If no proxy settings are made, a exception is raised internally which is later on caught correctly. If you've chosen to halt on exceptions at Tools > Debugger > Options however, you'll get the described exception, as the debugger stops before the catch block is reached. Your end users will never see this exception. You might either ignore the message or deactivate the option in the debugger's settings.
