Well I have noticed that with most programming that error messages are very 
obsure to the beginner.  Once you learn what to look for they start to mean 
something usefull.   ie Manageing to change the code to get different error 
messages is progress even if there are more of them!

But in this case I was looking in entierly the wrong place.  

I have found of late that it seems to be harder to get my brain around new 
concepts, and remeber all these new things.   I am hopeing that it is just 
over work, and that if I ever mange to slow down things will fall into place 
much more quickly again.  (Alternatively it couldbeold age - what alrealy!)

Even though I am visual I find it much easier to learn if someone explains it 
to me than just reading a book.  A lecture with some one drawing pictures of 
what they are talking about on the boad is fun to me!
