I've just tried to insert a screenshot into my previous MSO question.
I get the dialog box for choosing to upload from my computer or the web, when I choose "My Computer" and click the "Choose file" button, nothing happens.
This is shortly followed by Chrome freezing and AdBlock reporting it has crashed. I then need to kill off Chrome and restart it.
Chrome freezes even if AdBlock is paused.
I'm using the lastest Chrome (22.0.1229.94 m) on Windows 7 Professional x64.
Also get this issue on imgur.com, so not an MSO bug.
The issue was on my end, see my answer for full details.
