When going to the styles menu I initially only get the menu items in the left hand columns, the right hand side where the controls / buttons should be is completely blank, no associated controls appear. I can 'find them' if I move my mouse about over where they should be (the tool tips pop up), and then when clicking on one e.g. gradient the control then does appear. Changes I make in the plugin are reflected in the site.
I've just done a completely clean WP install with 2011, and using no other plug ins and the issue remains, any assistance would be appreciate.
