windows data editor changes dimensions displayed data frames

dear R-tists,

i am experiencing a problem with the data editor in the windows version of 
R 1.6.1 envoked with the command 'fix'.

the data editor changes the size of large data frames.

a simple example illustrates this:

-------------------------------------------------------

 > dfrm <- data.frame(no=c(1:100000))
 > length(dfrm[,1])

[1] 100000

 > fix(dfrm)

 > length(dfrm[,1])

[1] 34464

--------------------------------------------------------


does anybody have a quick remedy for this?

i am not sure whether it is worth putting much developmental effort in 
solving this particular problem.

however, i believe that one should be aware of it when working with large 
data sets.


greetings from the northern edge of europe.

bernd.
