Help

Post by Simon A. Platten » Thu Dec 12, 2002 10:22 am

I've posted something of this subject in another thread called compiler
error, however I'm not convinced it is. The problem is that I am finding
lots of problems when trying to debug any applications. I'm unsure why as
it wasn't a problem a few weeks ago, now almost everytime I add a breakpoint
and it is actioned I get a dialog telling me that an internal error has
occurred and to check the log file for details.

The log file contains the following:
