Hi Terence appreacte your support in my navigation in the MAC world.
I have remedied my problem by actually formating my HD and reinstalled a Time Machine from a few days back.
I have now 67 GB of free space!
There is something "invisibe" that expands taking up my space that is not reversed when closing/restarting my machine. I could not find anything unnormal using "Grand Perspective" but I really like the graphics and will continue using it.
I look at alot of movies during travels, do they build caches or similar using up "invicible" space?
Conclusion is taht problem is solved but I am as puzzle as before on what took up the balance of the free space..
Let's see going forward of it shrinks again..
