Protected Baseline issue in PS2007

[Patrizio]

I have cleared the "Save Protected Baseline" to the project managers group on
My Projects category.
Now project managers cannot save protected baseline, as desired, but they
cannot change timephased data on CURRENT values for BUDGET resources.
This is a big issue, because project managers must change current values
(not baseline) of the budget.
Is there any way to fix this issue?

Thanks.
