WA Guys: One for Justin?
I am able to see the problems you are getting with Opera. It works well for me in all other browsers. In Opera:
• The page load OK first time round. On refreshing the page, only the loader image shows.
• Clicking 'Next' will show the subsequent images, but these are displaced to the left.
• I need to close the browser and reload the page to see the gallery work as it should.
• Even then, the transition effects are 'stilted'.
I haven't seen this before, - I can't test it with another 'ribbon_fullsize' as I don't have one set up, but my grid & lightbox test page seems to function as it should.
Assuming that your implementation was quite standard, I think this is something that a WA tech (Justin?) needs to look at. Hopefully this will be picked up soon, once they get back into the office.
Sorry I couldn't be more help!
