How to use the CPU window for debugging in D7

问题

I have an unknown issue that causes the CPU window to appear. I have traced in the source to localize the problem to a call to MMSYSTEM:

FError := midioutClose(FMidiHandle); 

function midiOutClose; external mmsyst name 'midiOutClose';

I have never become proficient with the CPU debugger. There are no symbols, and I have no way of knowing what it is telling me.

Can anybody point me to a tutorial on how to use the CPU window of the debugger to find this sort of problem?
