Reinstalled IDM. Lets see what happens.
Lets hope for the best.
The problem is not solved
Tried all possible things, from disabling enabling IDM extension to re-install, adding tdf to exclusions etc. None worked.
The problem is really strange. The problem is only with Chrome and on TDF. All other forums working fine on Chrome. Even TDF is working fine on FF too.
Looks like I'll be using TDF from firefox and for other things I'll rely on Chrome.
Don't even know whom to report. TDF or IDM or Chrome itself..!!
