It is not even "last opened" - the blue highlighting disappears with 
time (not sure how long) - even if the folder is not touched - and it 
certainly disappears if RCM is closed and opened again . .

I guess that is what it seems to look like to me as well - but what does 
that mean for what I am trying to do? - ie reset the blue folder 
highlight arbitrarily?
