I'm hooked on Easy Fancybox!
Everything works fine except one day I happened to notice something funny when I re-clicked the link to open the layer in the same browser session.
I could see the browser content behind the text that I was trying to read, which made it really difficult. Videos the same way.
The only way to fix it was to reload the browser and click the layer link again. In other words each fancy box on my page only gets a one shot load to display properly (not be able to see through it).
I have WordPress duplicated on my off line Wamp server with the exact same settings,theme plugins etc, and it doesn't suffer the re-click problem.
Since it works right on the Wamp server, and not on my HostGator server, maybe it has something to do with server settings, which i wouldn't know the slightest about.
If there is no easy solution, I can live with it. Most of my visitors probably won't click the links twice in the same session. I do notice about half of them making return site visits though.
