I found a bug about sensitivity in the latest version 2.5

Dear mhscott,
In the sensitivity example , 2D RC frame subjected to earthquake base excitation (http://opensees.berkeley.edu/wiki/index ... excitation), If I used the opensees version 2.5, the sensitivity result of parameter fc,fu will be far different with the result by the version 2.4.6 (or earlier version). And from the result, I can tell that the result of 2.5 is not right . I use the FFD method to verify.
Another interesting thing is that if I calculate one parameter sensitivity like only fc in version 2.5, I would get the same answer with other version.
If anyone who ever had this problem, please tell me, thanks.

Every so often I found myself having to set the sensitivity lower and lower why it is so. please provide me detail.
