It isn't just EBAY.
I've just found that I get similar niggly things in my Moonfruit pages. When I click on a button, it looks like its working,,,,, highlights, or blinks or something, but after that - nothing.
Things seem better in Firefox, so I guess it is something to do with IE11. IE10 was fine.
Has anyone else come across this ?
Is it o.k to downgrade ?
