Hello Barney,
I'm fine thanks, and thank you very much!
If you check 'Just-in-time debugging' it means that whenever a program cause an exception (crash if you will), and you get a dialog saying something like 'This application has caused an blah blah exception and will be shut down' you will see an extra 'Debug' button in this dialog. If you press this button, Pelles C IDE will be started, the debugger will be started, and the caret/cursor will show the offending instruction. If the program contains debugging information you will see the source code, otherwise the assembly code. This will work even if you don't run the program from the IDE, it all happens through some magic Registry settings...
