General Description:
When I compare the timing reports from 7.x to 6.x, there are more paths listed in the report. Why?
The improved timing analysis tool in 7.1i analyzed more paths than 6.x version. These paths are valid.
This problem has been fixed in the latest 7.1i Service Pack available at:

The first service pack containing the fix is 7.1i Service Pack 4.
