On my boss's PC ONLY, I am experiencing an issue with rollover display on our new wordpress website. Rather than rollover to a green overlay on thumbnail images, the rollover images duplicate themselves above the original row. so essentially you are seeing 2 rows of thumbnails butted up against each other top to bottom. The issue only occurs on pages with rollovers, only on this website, and as mentioned before, only on his computer with FF and chrome. No other PC or mac in our office with this set-up has the issue. I have done the following on his computer: uninstalled firefox and chrome, re-installed firefox and chrome, cleared cache, cleared all extensions and add-ons, turned javacript on and off, The problem still persists. I did not code the website but I had the developer look at ti and he has not noticed anything off in the coding. He has the same set up as my boss and he does not see the problem on his end. Any suggestions?? Thanks.
