Noticed today that the PistonHeads forums appear to be loading something in the background on Safari - no performance issue I only noticed as my refresh button is replaced with a stop button.
I'm only replying as I can't find the original thread but it's down to pictures not loading on Safari again.
It's not always obvious but the page keeps trying to load and the pictures don't appear. Sometimes it completes but the pictures are just little blue boxed ? marks
