I am opening MYPHPADMIN and it does open, on the right end side I can see all the DB. Then I click on DB and does show all the TABLES. But when I try to use any of the TAB at the top of the TABLE: the table disappears, and nothing happens, it just sit there blank, then if I do an F% (recycle the page) it does bring back the table. How can get the TAB menu to work?
