Hello Michael,
Many Thanks for your suggestion..
But unfortunately this also did not work.
Below is the summary of my investigation -
1) Issue is faced in Windows 7 + IE8 as well as IE9
2) Checked and found compatibility option is selected.
3) Tried to bypass the cache, by pressing F12, click Cache -> Always Refresh from Server, it dint work.
4) There is something strange , sometimes the captions appear and after refreshing stops appearing. And sometimes it does not appear at all , not even for the first time.
Is this have something to do with Windows Media Player?
Regards,
Darshana
