Very strange for you to bring this up; I had the same thing happen to me on Friday when I navigated to the watched article page. I thought "no way Daniweb could have caused this" but now I'm curious. ;)
OK, so the watched article page eliminates the problem from being the editor. That's caused similar problems for us in the past that were tough to track down, so that's a big one.
It's possible there's a rogue ad that started showing up for both of you guys recently causing problems. Are either of you using an ad block? And do you have ads disabled in your profile? (Note those are two very different things).
I have ads disabled in my profile. Just happened again, it doesn't appear to be on any specific page. I don't have any ad blockers, the only web plugin I have is chrome's screen capture but that has NEVER caused any issues before.
The only link appears to be when I have been logged out. It was a full crash, I'm on linux so the entire machine locks and I couldn't bring up the terminal to kill the process.
