Today, I read about a problem with Opera’s onload event not firing when navigating with back / forward buttons. The reason for this is that Opera receives documents directly from cache. Another, similar kind issue is related to firing onload event, when adding images dynamically.
Currently, this is tested to work with Windows versions of Opera 10.1, 10.2 and 10.5 pre-alpha. Please, give me feedback if you find issues with other versions of Opera.
How to force refreshing
This isn’t complicated at all:
history.navigationMode = 'compatible';
How to solve image.onload

var test = new Image();
The key is to define src
you’ve bound event listeners.
