>What happens in Preview or Print? Do you get the same font as in the designer ( i.e the old one ) or do you get the new one? What font are you trying to change to? Does it happend when changing to other fonts?

This is reflected at run time as well. The font is Arial and I am trying to switch it from bold 12 to non bold 10. This is non bold. Whenever I do that, I see it ok. Whenever I go back in the report, it is reseted back to 12 in bold. All other changes are done ok.
