Dashboard drop down error

I know I should not have done that, but I did upgrade to Joomla 3.1.1 and everything things seems to work fine except this layout problem in Dashboard with the top drop down buttons. Is that because I have switched to 3.1.1 - do I have to do a fresh 2.5.11 installation...

Please make sure that you selected "above the content" in the "menu position" of HikaShop's configuration, that you have a recent version of HikaShop and clear your browser cache and it should then display fine.

Wow, yes that was it - now who would have thought of that. Thanks
