Profiler Not Reporting Reads Accurately

I am running a profiler trace against a database and noticed that the
reads column always shows 0. When running the same trace against
another machine I get back values in the reads column. I took a query
that profiler reported as having 0 reads and ran in in query analyzer
wtih STATISTICS IO on and confirmed that there are in fact reads:

Table 'tt_cawardalloc'. Scan count 1, logical reads 8, physical reads
0, read-ahead reads 1.
Table 'tt_clineitem'. Scan count 10, logical reads 125208, physical
reads 1540, read-ahead reads 2995.
Table 'tt_contractitem'. Scan count 32, logical reads 676, physical
reads 0, read-ahead reads 0.
Table 'tt_contract2'. Scan count 3, logical reads 121, physical reads
4, read-ahead reads 0.

I am on SQL 2000 sp3a. Any help appreciated.

Thanks!
