I cannot replicate this with the CRAN build of R -- here R version 2.14.0 alpha (2011-10-10 r57211).
Assuming that your reproducible example is
R
<Ctrl><Z>
fg

It works just fine (both xterm and Terminal). So

a) can you, please, check the CRAN build of R and see if you see the same problem?

b) provide exact details about how you compiled R (configure flags) as well as all 3rd part libraries you used so we can try to reproduce it?

Cheers,
Simon
