Missing quicktime plugin..drives me crazy

Hi 2 all,

I am on 10.6.8., macpro early 2008.

Whenever i want to see a quicktime movie on a site in safari, it shows met the missing quicktime plugin question mark.

However, I looked in the internet plugins folder and the quicktime plugin is really there.

I tried several things:

- re-installed quicktime 7.6.6

- removed all internet plugins except the quicktime plugin from the internet plugins folder.

- deleted safari preference file

- deleted quicktime preference file

- looked at the permissions for the quicktime plugin ; they seemed ok.

- de-installed perian.

I googled around for the problem and it seems i am not the only one, but i couldn't find a solution that works for me.

BTW: i already had the problem in 10.6.7, so upgrading to 10.6.8. (combo update) didn't make difference.

This is really driving me nuts.

Does anyone has a briljant solution for my problem ?

I very hope so..

Thanx in advance !

Kind regards,

Rob.
