Hello Petr,
I use Safari as browser, empty the cash, BO and FO.
Thanks to explain the option to see some lines in the reviews.
The delete option, are no great issue to me, I understood your point of view.
The only thing I come back are that when I write a review and click to accept the review, the popup give a negative state. When I reload the page again (browser), the written review come up, strange. I think it have something to do with Zend cache on the server.
