Technology Illiterates

There seems to be something of a routine forming in one of my classes.  The teacher likes to use the projector, to show us video clips, or simply an audio recording.  However, whilst she appears quite capable at using an office suite, and surfing online, anything further is beyond her grasp.  So for the last couple of lessons, she has started the computer, only to run into problems.  No-one else in the class appear to have any inclination to attempt to fix the problems.  So, whilst I struggle with the aim of the class, I'm willing to sort this out, if only to get on with the lesson.  However, I do wish that the teacher would watch, so that she might work out how to do it herself.  I don't particularly care to make a habit of this!  

I generally find that providing you know how to get back to an initial state, messing with computers does very little damage.  I only wish more people took a similar attitude.
