From my earlier post, you can tell we are having some issues with large drawings.  Last night, put the SW to bed with it's warm milk and bedtime story only to awake this morning to a new more frustating problem.

All I did, after saving and shutting down yesterday was open the exact same file.

As you can see, ALL functions are greyed out and therefore I can not anything whatsoever with my near complete file.

I open another file and all works as designed.  I open in another computer with the same greyed out functions.

GRRRRRRRR
