OK Update.
It was the antivirus and when it updated it reset something in the safe browsing part that should not have been sent out with the update. One little check box has been changed and all is hunky dory. So now I'm back to rebuilding my website with drop down menus, thumbnails that open, even BIGGER and even better.
It's been said before and I'll say it again.
No matter if you have probs with computers, engines, fridges, a wife that is malfunctioning, a screwdriver that you don't understand or discharge from your wee hole - There is always someone to help out... Well maybe not the latter.
Cheers Guys and Gals.
FOC-U YOU ARE AWESOME.
