I don't have LVM partitions - at least, I never set any up!!!

Yes, mine is similar

Indeed:
free -m
             total       used       free     shared    buffers     cached
Mem:         3709       2013       1696          0        102       1139
-/+ buffers/cache:        770       2939
Swap:         1999          0       1999

Thanks all for the many suggestions!

Strangely, just after I sent my original mail, System Monitor suddenly 
decided, all on its own, to add the 2GB swap partition....???????  I

Anyway, things appear to be (back to) "normal"!

Thanks again
