Thanx for the idea Chris.
As you said i created a new account by the name "darkmagic" & then logged in using that account & everything worked as it should be.
Then i logged out from "darkmagic" & logged in using the "tarun" account, but then the "tarun" account was still having problems.
Then i logged out of "tarun" & logged in again using the "darkmagic" account but it was working good again on the same computer with the same settings.
Then i again logged out of "darkmagic" & logged in using "tarun" & the problem was still persisting.
So, i guess this is something specific to the account.
Is it possible for you to delete my account i mean the "tarun" account & then recreate it, with the account still maintaining its properties, but i don't really want to loose my registration date & no. of posts :wink:
And yes you can safely remove the account by the name "darkmagic".
Thanks again.
