Contradictory Display of parameter shared_pool_size?

Question

Hello All,
I want to change the value of the parameter shared_pool_size. I am on Oracle 9i and I confirm that dynamic SGA is activated.
I use brtools to change this parameter and use scope=spfile.
After I change the parameter I go back to the Display parameter menu and when I display this parameter value it shows,
Parameter value=<old value> Why?
Value in spfile = <new value>
when i give the cmd show parmeter from SQL prompt it displays <old value>. Why???
Now even if i use scope='memory' or 'both' the outputs are,
In brtools Menu,
Parameter value=<old value>
Value in spfile = <old value>
and through sql prompt -> <old value>
can someone please explain?
I understand this parameter change doesnot require a restart because Dynamic SGA is activated but even a restart of DB doesnot help.
Thanks,
Bidwan
