Can you post a screenshot so we can see what's going on?
plz help me in this problem...Allow And deny box Dosenot Appear...???
Chrome has recently introduced a number of changes to how and when the browser chooses to launch Flash Player. In this instance, my guess is that Chrome has decided to not instantiate Flash for this page. Since Flash Player is never launched, we never get to ask for permission to do anything, and therefore Chrome does not display the Allow/Deny dialog.
You can try to change this behavior in Chrome by going to Menu > Settings > Advanced > Privacy > Flash > Allow Sites To Run Flash, then reloading the page.
If that doesn't work, you may need to disable the PreferHTML feature in Chrome to restore the desired functionality:
Go to chrome://flags/
Search for "Prefer HTML over Flash"
Allow and Deny Buttons are invisible to meit is not appear help me plz
