thanks for the info complich8. i don't have RMA; i purchased it from a computer store and they didn't give me any warrantee card; the receipt will serve as the warrantee. i've verified it with another computer and same problem occured.

Just returned it to the store the other day, they said it'll take 2 to 3 weeks for testing; if there is a prob with the lens then a new one will be given to me. Sounds good, but i got a long time of waiting to do.

paulyboy, i checked for an update but there is none.
