[R] Problem with MASS data

I have run into a problem accessing data sets in the MASS library.  Not sure why...
I still have R version 1.1 installed on several machines and have no problems.  However,
I installed R version 1.2 on three machines today and could not access data sets in 
the MASS library on any of the machines.  The file directory indicates the data sets
are in the correct location ... but R says:

> library(MASS)
> data(cats)
Warning message: 
Data set `cats' not found in: data(cats) 
> data(Boston)
Warning message: 
Data set `Boston' not found in: data(Boston) 

The problem seems to be only with the MASS package.  

> library(boot)
> data(aids)
> aids
    year quarter delay dud time   y
1   1983       3     0   0    1   2
2   1983       3     2   0    1   6
3   1983       3     5   0    1   0

After typing  

the data sets I should be able to access appear....

Data sets in package `MASS':

abbey           nickel in syenite rock
accdeaths       US accidental deaths 1973-8
Aids2           Australian AIDS survival data
Animals         body and brain weights from Rousseeuw & Leroy
anorexia        anorexia data on weight change
austres         quarterly series of the number of Australian residents
beav1           time series of body temperatures of two beavers

Have I missed something in the new release?  Any ideas?
