Anyone else have this problem? I log in and my username appears as usual. Then after viewing some clips decide to comment. But for whatever reason after typing my comment in the box, just stays there when click on post with the cursor flashing.  

Only recently this started happening. Posted comments many times before. I've used to contact us link to report this fault and awaiting reply or fix. So anyone else experiencing same?

Fixed. Noticed someone had posted on the clip yesterday, so tried again today. Successful
