I recently switched from Internet explorer 7 to I.E.8 . I had tried I.E. 8 before and had experienced some problems operating some programs but thought that maybe I would give it another try. Well once again I am having problems and would like to switch back to I.E.7 but when I try to download I.E.7 it tells me that I already have it . How can I dump I.E.8 and return to I.E.7 ?
