I cant try 'top' on the target machine till tomorrow, but it
sure acts strange on my machine here at home when I test it
right now.

While running interactively, all the interesting fields at the top
(like Mem) are BLANK. 
Stopping it, still blank.
BUT, if I use the mouse to copy the top of the 'top' display
somewhere else, (like this message),
then the fields are filled in with what appear to be
correct values.
STRANGE.
Ive NEVER seen anything like that before.

But will try it on the target machine tomorrow.

Any other thoughts?
